Firefox 4 comes with everyting

The development of Firefox 4 is advancing by leaps and bounds: anything that claim at the time and made many of us move on to Chromium, not without feeling a pain in the chest when doing so has been taken into account by developers Firefox. The visual enhancements, speed and standards support are absolutely breathtaking.

New features in beta 7

• Jaegermonkey: New JavaScript engine, already used in the latest beta of Firefox Mobile. With superior performance V8 Nitro Safari Google and in most cases.





• Hardware acceleration in Windows: reverted to Direct10 Direct9 where working (Windows Vista or higher). In addition, activated Direct2D to further improve the rendering of pages. You can check on the page about: support in the graphics section. (If disabled, for example, put 0/1 in the latter, may be due to your drivers for video card are outdated and are marked as faulty by Mozilla, so you have to update to the latest version from page of your card, we will talk more about that in later entries.)


• Mac hardware acceleration, using OpenGL, which helps greatly in the speed


• Removed the status bar, replacing it with the bar-ons and hidden by default, so now when you hover over a link, the page that we go instead of being shown in the bar is shown in the
  address bar.


• Improved rendering of fonts with OpenType, which allows the use of kerning, ligatures and variants.


• HTML5 forms, with validation (without JavaScript!) And other interesting things.

New features in the next beta 8

The latest version incorporates Linux finally unified menu. Apparently this was not possible before because Xulrunner could not draw in the title bar (where the button on Windows). This, in turn, is due to certain limitations of GTK2. For that reason, but now added the button, it appears below the title bar.

To test this new version and keep updated, add the Mozilla repository daily.

sudoadd-apt-repository ppa:ubuntu-mozilla-daily/ppa
sudo apt-get update
sudo apt-get install firefox-4.0

Note: Beware! Although not necessary, you should uninstall version 3.6 before adding Firefox 4. In case you do not want to, you can download this version by hand.
