Chromeless: Build your own Browser ,Create an interface for Firefox

Firefox improves interface in all versions out, but developers want their users to have even more freedom. For that reason, are working on an "experiment" called chromeless, where you can develop an interface to the browser, implementing the options that you look good. For the time is pre-Alpha stage, but have a version that can be tested to see their idea in mind.


Although the browser version to version upgrade their interfaces to make them easier to use and powerful will always be ideas that you want to implement, but never arrive. It is for this reason and more, which Mozilla has started a new experiment called chromeless, which has little to do with the Google browser, and much to let the user design their own interface for Firefox.

As explained in his blog, the Firefox interface is designed using XUL and XPCOM, which allows developers to deploy new high efficiency. But of course, that does not mean that it is easy to any user of Firefox developer and want to change some aspects of the browser interface. Functional version available, uses iFrames instead of XUL elements and therefore not free to expect the final product.

From an HTML file
For now, try the current version pre-alpha, which is a mixture of Lab Cuddlefish Atul Varma, Jetpack SDK and XUL Runner. And although not exactly what they want, they can show they want to reach the goal. The application runs from an HTML file and has special privileges such as access modules CommonJS by Jetpack platform. Anyway, it is clear that this is just temporary until they can go further in development. What is lacking?

They are currently testing a pre-alpha version able to load HTML pages and render the browser interface. The next step is to add APIs (application programming interface) that correspond to specific user needs to build their browsers. Then, investigate ways to integrate security features and finally create a SDK (software development kit) available for anyone to edit the interface of Firefox can do it smoothly.

Firefox 4 is delayed until early 2011

The next version of Firefox, Firefox 4, scheduled for late 2010, is delayed until early 2011. This change has been announced, through the Mozilla discussion group on Google, the director of Firefox, Mike Beltzner, who notes that Firefox 4 will end is taking more work than originally estimated.


"The beta versions have been very helpful in identifying problems of compatibility with existing web content, so it is planned to follow the beta releases until the end of December. Our estimate is that Firefox 4 comes in early 2011," says.

Six Betas have arrived in recent weeks, but the version of Firefox 4 beta 7 is not submitted. One of the big problems has been the integration of the major TraceMonkey javascript engine to run Web-based programs, and new JaegerMonkey engine based on Google V8 engine in Chrome.

Version 4 of the second most popular browser includes several important improvements. Redesigned user interface includes HTML5 format, a hardware accelerator for high-definition video and as anticipated, the function 'multi-touch '.

Need Mozilla Firefox 4 out sooner because the market in recent months.

MeeGo 1.1 has been released

Vineyard, an aid to improve Wine


If I said I used Windows for anything ... I'd be lying terribly. Unfortunately it is not a perfect world, because if it were you could use Linux without worrying about the famous compatibility with that program. Or I could play Age of Empires in Ubuntu natively. But since it is so, we have Wine.

But we have a "detail." Its interface is perhaps too "technical." If you're new, it is clear so you can navigate unknown option. But do not despair, there is a more friendly, named vineyard.

To install, open a terminal and add the repository to the list
  • sudo gedit /etc/apt/sources.list
and paste:
  • deb http://ppa.launchpad.net/cybolic/ppa/ubuntu lucid main
  • deb-src http://ppa.launchpad.net/cybolic/ppa/ubuntu lucid main
Then update and install with:
  • sudo apt-get update && sudo apt-get install vineyard
To install on Maverick, open a terminal and add the repository:
  • sudo add-apt-repository ppa:cybolic/ppa sudo apt-get update sudo apt-get install vineyard
You can access it from System/Preferences/Wine Applications:



With this interface you can uninstall programs, select the preferred audio codec, to emulate the operating system you want ... There are many options, so you just need to start.

The videos uploaded to YouTube can be viewed WebM in WebM

From now on, the videos are uploaded to YouTube in the new format WebM, can be displayed on WebM.

This was one of the points that were missing on Youtube in its slow but steady Expension WebM the availability of its beta of HTML5.

So far the user who uploaded the videos could not see if your videos would be available in a free format.

Only those who had a resolution of 720p or higher were seen really WebM formats.

From now on any video uploaded in that format, regardless of resolution or popularity may be seen in WebM.

This would open a door for other videos uploaded in free formats such as Ogg/Theora format can also be seen in WebM.

If you upload a video in this format, make sure the entries are disabled, to make sure advertising can be viewed without Flash or H264.

Tip: How to unzip files on Linux


To unzip files in graphical mode, users of GNU/Linux have several tools and file manager that we make the task easier. But to perform these tasks from the console, first chance we have to know how to treat each of these files.

Let's look at how you extract individual files compressed or packaged in Linux from the console.

Tar

Tar is a file format used in Unix environments that are identified with the tar extension. The tar program is used to store files and directories in a single file. To extract it from the console, we run the tar command with their respective options: x (extract) f (from file), and optionally v (see what is done).

Example:

  • $ tar xvf archivo.tar
Gz

GNU zip or gzip is a compressed file type is typical of Unix systems. To decompress, we do with the gzip command and their options: -d (decompress) , -f (force). Or use the gunzip command, which is a link to gzip.

Example:

  • $ gzip -d archivo.gz
  • $ gunzip archivo.gz
Tar.gz

Is very common to see Linux files packaged with tar and compressed with gzip (.Tar.gz). To decompress, we do the same way as a tar file, but adding the z option to tell the program to use gzip to decompress.

Example:

  • $tar xvzf archivo.tar.gz
Bz2

Atchivo is a type of compressed with bzip2. The syntax is similar to gzip program. To decompress bzip2 command is used with the -d (decompress), or the bunzip2 command, which is only a link to bzip2.

Example:

  • $ bzip2 -d archivo.bz2
  • $ bunzip2 archivo.bz2
Tar.bz2

Similar to the tar.gz file, but used bzip2 to compress. To decompress tar is also used, with the option j.

Example:

  • $ tar xvjf archivo.tar.bz2
Zip

Zip compressed file. Decompressed using the command unzip:

  • $ unzip archivo.zip
Rar

Proprietary format developed by the creators of the famous Winrar. In most cases, the rar command is not installed on your system. For this tipeamos following in console:

  • $ sudo aptitude install rar (In Debian / Ubuntu)
  • $ yum install unrar (In Fedora)
To decompress, we do with the -x (extract).

Example:
  • $ rar -x archivo.rar
7zip

A data compression format free. To use it, we install the following package:

  • $ sudo apt-get install p7zip (In Debian / Ubuntu)
  • $ yum install p7zip (In Fedora)
To compress:
  • $ p7zip nombre_archivo
To decompress:
  • $ p7zip -d nombre_archivo.7z

How to Block Websites on Firefox with Password Protection


Many times we need to block access to a website for some reason, either because the content is inappropriate for him to watch, because we are distracted, or whatever the cause. LeechBlock is a Firefox extension that allows us to block access to a website.

The extension is very configurable, but with a couple of basic options can block any site during a given time interval, the amount of time you want, the days you want.

When someone wants to access any blocked sites will see a message like this:


The good thing is the safety LeechBlock, allowing us to protect settings with a password extension, thus preventing any apueda remove the block, and only we can change these settings.

How to Install Ubuntu Maverick Meerkat (10.10) STEP BY STEP With Pictures

Well my friends, I always start the new version special explaining how to install. What makes it no less important to explain step by step.

As always, for writing this tutorial NOT USE THE FINAL VERSION for reasons of time. I used the Beta version released in September. as in many steps, things have not changed.

If you want to see the innovations that bring Ubuntu 10.10, can check this post ... In general, there are great news indeed, but is a step forward and appreciated.

First: Download Ubuntu

To download go to the Ubuntu download page:


Now you can download the latest version, which is also LTS. For those not familiar with Ubuntu, the difference between the last version and the LTS (long time support) are the months in which maintenance is performed. The Long Time Support is for 36 months, and which are not maintained it for 18 months.

After choosing the latest version, look for a place near where you live to download the image. Click Begin Download, and start downloading. After downloading the image, burn it onto a CD or a flash drive (this version is for users who already have Ubuntu: System/Admin/Boot Disk Creator) and are ready to install.

Install Ubuntu 10.10

Put the CD or flash drive in your computer and restart. set it to boot from the CD or Flash Drive. After a moment to load, it will open the installer:

The first thing I ask is that if you want to try Ubuntu without installing it or install it directly. If you want to modify a previous version installed, choose the second option in order to access your partitions.

After selecting the option, it will start, now, the installation wizard:

After selecting both the language and keyboard, will show you what you need to install Ubuntu:


Now, we proceed to partition the disk:


This stage is what one might call the more "complicated." And it is in quotes because if you read carefully what you said, you have no problems. However, there are more advanced options that require time and patience to master.

To install Ubuntu, we have 3 options:

Ubuntu and other operating system

For this option, choose Install next to the other, choosing between them at every boot. If you do it this way, each time you start your computer you will see a black screen that lets you choose which system you want to upload. Among them, the alternative system.

Only Ubuntu

If you want to just install Ubuntu, choose the second option. Ubuntu install from scratch, but not split your drive (hey, this is important. Later I will explain why)

Partitioning "A hand"

If you choose this option, you can edit your partitions, select the file system that best fits your needs, and give the size you want your partitions. In addition, there is something important you can do: you can separate your system partition of your documents. This allows you to reinstall Ubuntu from 0 without having to remove your documents.

SUPPORTS YOUR DOCUMENTS BEFORE YOU DO THIS IF YOU ARE A NOVICE. AN ERROR MAY DELETE YOUR DOCUMENTS, AND TO THAT NOTHING CAN BE DONE. IF YOU ARE ADVANCED, YOU KNOW THAT THE RISK TO PASS SOMETHING is very low, BUT ALWAYS IS. ALSO DO SO.

Creating my partitions

To create partitions, you have supported all your documents, because this involves clear your system. Except you've done it before and want to keep your home.

I recommend that if you are installing only Ubuntu, divide it into 3 partitions:
  • The first will be the system partition, or /. Its size is at least 3 gigabytes. Why? 2 gigs are needed to install the base system, and leave a bit to install programs. But if you're going to use only Ubuntu, I recommend that you put at least 7 gigabytes.
  • The second is the partition where are your documents, or /home. This size you put it, and depends solely on how much you're using Ubuntu.
  • The third is the partition swap. This partition must be yes or yes. To know how much space we give you, the Ubuntu Guide recommends the following rule:
  1. For partitions 1 gig or less, the swap should be twice your RAM. So, if you have 512 megs of RAM, your swap should be 1 gig.
  2. For partitions of 2 GB or more, the swap will be half of your ram (Editor's Note: This is a bit outdated, if you have more than 2 GB, leave only one)

If we do as I said, it should be something like this:


To create a new partition, select the new partition table:


  • First, choose the type of new partition: Primary or Logical.
Primary partition allows the system load. Logical partitions are used to having multiple partitions, for example, have separate documents partition.
  • Then choose the size you want for your partition. Remember what I said earlier.
  • Then choose the location of the partition. For the system (/) elected at the beginning, and to choose the final swap (/)
  • How we choose to use the file system you wish to use. For version 9.10 version includes ext4 by default. and I recommend them 100%. . Those who use Ubuntu for a while we noticed the difference. Sides view the files in the Linux partition in Windows do not choose this option in the partition of your file (/home), and there are no programs for the moment that you can detect, better choose ext3.
  • Here we can also choose the mode swap (swap partition). When you do not go below anything else. Do not worry, and click on OK.

Now we have to choose the mount point. Follow the instructions below:
  • For the system partition, select /. When you leave, select the Format option


  • For the partition of your documents, choose /home. If you are updating your Ubuntu partition and previously had a home, when you leave the format option is deselected. In this way, you can collect your documents and settings and desktop programs.
  • If you have a Windows partition, will appear as NTFS. You can edit your free space to give to Ubuntu. However, I recommend that you back up your files. You never know ...

If you did not like what you did, you can click Undo changes to partitions, and everything is back to normal. If you're ready, click Next.

Now, while installing, you can configure the system which is great because you can save much time. And if you install via USB stick, you take much less. Start by setting the time zone:


We then went to configure your keyboard:


Click Forward. Here we put our personal data, the password you will use (and also will be the default for our system permissions, so do not forget) and our name on the network.


After that, it will make a tour of what Ubuntu is and the advantages that account to install it:


After a while, Installed System! When finished, you will have to restart the system:


Well gentlemen, after these steps, and restart, we will have installed Ubuntu.

Well, with that special finished the new version. Tutorial installation and configuration, all in 1 day. Later discuss the details of this version on computers

That. Greetings. And enjoy Ubuntu!

How to control the amount of RAM used by Ubuntu

With the arrival of Ubuntu 10.10 (probably) on Sunday 10/10, it is expected that a large number of people want to test the system, installing or upgrading from an older version already installed. So, knowing that such a trick to optimize memory usage in Ubuntu?

First of all, a quick explanation: Linux by default uses a special partition as swap memory system, and maintains a standard configuration, regardless of how much RAM you have on your computer.


Thus, in a post-installation, regardless of whether you use 1 or 4 gigabytes of RAM, the system will always use a standard percentage and allocate the rest to the memory swap. The problem is that if your machine has too little RAM, can be more interesting set the system to use more swap memory and thus be able to run multiple programs at a cost of some performance. Otherwise, if your machine has RAM to spare, you may want to use it the most.

This is where you enter the parameter swappiness. He defines, in Linux, how much RAM is used. And this setting can be changed as needed by the user. To determine the current value of swappiness on your machine, run the following command in Terminal:
  • sudo sysctl -a|grep swappiness
The result screen should look like
  • vm.swappiness = 60
And what's that worth? Swappiness parameter can have values ranging from 0 to 100, where:
  • 0 tells the system to allocate as much resources as possible directly in RAM
  • 100 tells the system to allocate as much of that is not currently in use by the memory swap

So, if you set this value to around 100, the programs will start faster, because there is plenty of room in RAM. On the other hand, values close to 0 will cause programs to behave better after opening.

And what is the best value to use? That depends entirely on you, the equipment you are using and the programs you want to rotate. The best way to find out is to go slowly changing values until you feel that the system is the way you like.

To change the value of swappiness, run the following command in Terminal:
  • sudo gedit /etc/sysctl.conf
The configuration file opens in text editor. Now, look at vm.swappiness parameter and change the value that is there. If the parameter is not in the configuration file, you can type it out like this:
  • vm.swappiness = “XX”
Where XX is the value you want to use. Restart Ubuntu and see if the programs are behaving the way you like. Otherwise, change the values until you get to your liking.

Updating Ubuntu from 10.04 to 10.10

Well today is a date marked on my calendar (the explanation), so I downloaded the image from the new version of Ubuntu, and all ready I realize that I have no cd virgin nor any pen, as the desire to test were stronger I try to update from the update manager but does not give me the option, after this couple of disappointments began my search our beloved Google and I find the following solution:


Type Alt+F2 (Run Application) and writes:
  • update-manager -d
Update Manager appears with a new option:


Select the Refresh and ready to wait a couple of hours (my connection) to have your equipment with the latest version. Remember that nobody is perfect, so backing up your files, and save us surprises.

Until next time, for now look for a cd or a pendrive to format the partition and try Ubuntu from scratch.

Ubuntu 10.10 is now available: What brings them back? Is it compatible with my computer?


As we all probably know, and for which there also, today -10/10/10- at 10:10 hours has released the latest stable version of Ubuntu: 10.10 Maverik Meerkat. Thus, the popular distribution based on GNU/Linux and focused on desktop users and mobile devices, closed its development cycle of 6 months to see the light, and with it, this post.


Much has been said about Ubuntu lately. That if necessary install the latest version, whether it is feasible to release a new version every 6 months, etc. But let a little aside all this, and let's see what improvements we bring this distribution has both joined the global free software community.

It is noteworthy that the release of Ubuntu 10.10 Maverik Meerkat also coincided with the parallel and official editions: Kubuntu, Xubuntu, Edubuntu, Mythbuntu and Ubuntu Studio.


Which brings us back to Ubuntu 10.10?

There are many improvements that brings Ubuntu 10.10 Maverik Meerkat, in addition to the visual aspects that are already undergoing changes from version 10.04. So let's list the top 10 highlights of Ubuntu 10.10:


  1. The installation easier than ever: The Ubuntu installation process was simple and its earlier versions, but has now been further simplified. Now we are asked only what is necessary. In addition we will be clearly informed what is going to do the installer and what are the requirements for each operation.
  2. Center Ubuntu Software: The Center Ubuntu Software began as a simple addition of Synaptic and APT system. But from this new version, it will handle much of the installation/upgrade packages also offer a very attractive visual interface with complete descriptions of the applications.
  3. Ubuntu One with audio streaming: this service in the cloud storage and file synchronization has expanded its services with the inclusion of Ubuntu One Music Store to buy and distribute music:
  4. The typography: a significant change visually is use of a free font and property of the distribution: Ubuntu typography.
  5. Unity: Another major change is related to Ubuntu users netbooks and notebooks, which can access the Unity interface, specially designed for screens with limited resolution in which the maximization of the resolution is key.
  6. Notifications: notifications have been improved with a renewed form of appearance with a new iconography, and above all more clear and complete menus.
  7. Shotwell: F-Spot has been abandoned in this distribution giving rise to Shotwell, a very ambitious program that aims to become the perfect photo manager for our GNU/Linux.
  8. LibreOffice: the fork of OpenOffice.org called LibreOffice, will be the default suite of Ubuntu 10.10. In this way, Canonical demonstrates its support for the office suite.
  9. Btrfs: a file system that is currently not used natively and by default, although it does MeeGo. In Ubuntu 10.10 we can create partitions with the file system Btrfs to take advantage of a development that could happen to ext4.
  10. Gnome 2.32 :the Gnome 2.32 desktop environment will surely be the last version of 2.x family will see before the release of Gnome 3.0.

Is Ubuntu compatible with my computer?

Fear of our hardware incompatibilities with the various Linux distributions, is one of the major barriers when migrating to Free Software world. It is also true that Ubuntu works on most computers without requiring major adjustments to the hardware after installing the system.


But to further improve this area, Canonical has launched an initiative called "Ubuntu-certified hardware", which allows the user to know in advance what equipment manufacturer which works perfectly in Ubuntu.

This we can save a big headache if you're thinking of buying a new computer to work with Ubuntu.

Ubuntu-certified hardware is divided into 3 parts:

  1. Ubuntu Certified: They have this certification for computers that have been tested first hand by Canonical, performing positively all relevant compatibility tests.
  2. Ubuntu Enabled: This certification is present only on computers that are compatible with Ubuntu by Canonical introduces some modifications, ie equipment that initially are not 100 percent compatible, but that Canonical and makes.
  3. Ubuntu Ready: This is a certification given to those computers without going through the hands of Canonical, has been certified 100 percent compliant by the manufacturer.

So before making a new purchase, take a tour of Ubuntu-certified hardware. a enjoy Ubuntu 10.10 Maverik Meerkat!

[Updated]
It is clear that the list published by Canonical Ubuntu-certified hardware is not an exhaustive list by any means. It's just a list of certified hardware company behind the Ubuntu Linux distribution. Moreover, any hardware device market is capable of running either Linux distributions available today. And if we are not very expert in the subject, with the help of the community we run our computers with GNU/Linux to 100 percent.

Guake, a terminal "top-down" for Gnome


For those who make daily use of the terminal or text console on GNU/Linux, there is nothing better than having to hand the integration of the best possible way to our desk. Users of the Gnome desktop environment Guake have a terminal style " drop-down " or " take off ".


What is this? Simple. Once we run Guake, this is kept hidden until the call by pressing F12, that will be deployed from the top of the screen. I think there is no better way to have at hand the terminal in our system GNU/Linux.

Guake can also use several terminals at once using tabs. It is also possible to configure it to adapt its appearance to your desktop. It has a Preferences menu, where we can change their appearance, keystrokes and adjust to your tastes. Yakuake very similar to the terminal for KDE users.

Installation is very simple. In its official website indicates that packages are available for distributions as Fedora, Debian, Ubuntu and ArchLinux, which can be downloaded from the Downloads section.

Failing that, you can install this terminal from a terminal. Let's look at how.

In Debian/Ubuntu:

  • $ sudo apt-get install guake
In Fedora:
  • $ yum install guake
To enjoy this great terminal.

Get higher screen resolution with NVIDIA drivers in Ubuntu


This is a problem I have with my PC, Ubuntu and Nvidia drivers after every installation I do a new version of Ubuntu.

My desktop PC has an integrated graphics card Nvidia GeForce 6150SE nForce 430, the problem arises after Nvidia drivers installed, and I can not get a higher resolution than 1024×768, someone will say it is a resolution so low but for me that I get to use 1280×1024 if it is.

Than any mortal ? Would be to go directly to nvidia-settings and from there change the resolution, the problem is that we allowed to change the resolution but want to record, returns this error.
  • Failed to parse existing X config file '/etc/X11/xorg.conf'!
We solve it as follows, after installing Nvidia drivers have to run the following command:
  • sudo nvidia-xconfig
This command modifies the /etc/X11/xorg.conf for nvidia-settings and change it to read it, now you can change your screen resolution from nvidia-settings
  • sudo nvidia-settings

Mozilla includes Bing in the search options of Firefox 4


This morning, I read something that surprised me and soon realized it was not correct information.

He meant that Mozilla had reached an agreement with Bing, the Microsoft search engine, to be your default search engine.

Actually, I missed a lot and then saw that it was just an error of the informant and that it was only included in the box where we choose the form, ie as a more standard option.

The default search engine will be Google.

This addition is planned for the new version of Firefox, the number 4, in this way, users can choose Bing in the pack to put it as your search engine, without any further configuration.

where I saw the news now published, is much the money that Google pays to Mozilla to have a privileged place as a search engine in Firefox, say that is the main income source Mozilla.

But Mozilla, makes clear with this decision, that it does not influence their decisions when choosing the other options.

In this way, search engines that will be included as options in Firefox 4 will be Amazon, eBay, Wikipedia and Yahoo. Creative Commons and Answer, are out for version 4.

Cleaning Ubuntu: commands and programs


One of the things I do not like about Ubuntu is that it builds a lot of garbage. When you uninstall a program, the settings stay. When you upgrade, the setting is. That becomes a very uncomfortable situation.

But Ubuntu has slowly been correcting these problems very easy to use applications, without leaving command to delete existing data from the terminal.

Talk about some commands and programs, the most useful. If you know one, let me know

Clean command (via Terminal)

1- Every time you install from Synaptic or upgrade your Ubuntu, the packages you download from Internet are in /var/cache/apt/archives. If you do not delete them, build up space that can be quite useful. If you want to completely erase type
  • sudo apt-get clean
2- Many programs that use install additional units that discharge, and often useless. Worst of all, when you uninstall are sometimes taking up space. To know what to delete and type
  • sudo apt-get autoremove
3- Each time you update your kernel, the old is there, and will not uninstall. If we delete, we can do with
  • sudo apt-get remove --purge linux-image-versiĆ³n a desinstalar-generic
If you do not know what we want to uninstall, we can list them with
  • dpkg --get-selections | grep linux-image
Cleanup Programs
Fslint



If users are those who walk disorderly leaving empty folders, duplicate files around the computer or temporary files, FSlint is your program.

With a friendly interface helps you with that and many other things, among them, delete the thumbnails of your photos (which accumulate with every device that mounts), and accumulated an impressive amount of trash.

To install the terminal type in
  • sudo apt-get install fslint
You can access it from Applications/System Tools/FSlint

Ubucleaner

Ubucleaner is a script that is used, for cleaning and maintenance of Ubuntu. Roughly speak executes commands at first, deleting the older kernel and files that are stored in /var/cache/apt/archives. It also eliminates the paper files of all users.

To use, download the script from this link. Then enter your property, go to the Permissions tab, select Allow to run the file as a program. Now you can run it. For this open a terminal, go to the folder where the program writes
  • sudo ./71529-ubucleaner.sh

From there the script will ask you some things, so it's not plain sailing ...

BleachBit


This is the last puff of mate. BleachBit is an impressive program, because with it you can erase everything that can be garbage, history, temporary files, thumbnails. And not just Ubuntu, but many programs: Firefox, Flash, Openoffice.org, Gimp, etc.

Installation is very simple. Download the program from here, where you can select your favorite Distro. Once executed, you can run it from Applications/System Tools/BleachBit. Eye may also enter with Administrator privileges.

Ubuntu Tweak

At this point there is little that this program can not do. And with the latest version has added the option of cleaning:

Does not have as many options as BleachBit, however, for the user that starts is probably all you need.

Well my friends, that was it. I tried to see the most used, because the list is endless. I hope you have enjoyed, we are.

According to an independent study, Firefox is the best filter for malicious sites


Security is very important on Internet and your favorite web browser also looks at that aspect. The site Hispasec independently conducted a study to test safety against fraudulent sites, in most popular browsers: Firefox, Chrome, Internet Explorer and Opera.

The study was very simple. 20,623 were trying to access from various malicious web browsers. For this, each browser has different methods of protection, among which most common is black list of fraudulent sites, where each browser has a kind of repository that blocks malicious sites.

What conclusion reached? Of 20,623 malicious web pages, Firefox blocked 35.08% (7108), Chrome 32.76% (6639), Internet Explorer a 25.39% (5,114) and Opera 8.34% (1690). That is, Firefox (followed closely by Chrome) is browser that blocks most sites, while Opera is worst of four, even worse than Internet Explorer.


According to report, all URLs were detected as malicious by any of browsers. But then, what is problem? Why is there so much difference in data? The problem is clearly in low or no predisposition of some of parties to work together. For example, it often happens that detected malicious URLs in Firefox from being detected by Internet Explorer or Opera and vice versa. If there is a universal filter, created and maintained by all browsers on market surely situation would improve for everyone.
