Mozilla Firefox 4.0 Beta 1 Now Available for Windows, Linux and Mac OS X

Promising to be faster and stricter with the current and upcoming web standards, as well as adding the new WebM video standard that’s been put in place by Google, Mozilla Firefox 4 is the new face of competition from the Mozilla Foundation for what will be your next version of your favorite web browser.

What’s New in Mozilla Firefox 4.0 Beta 1:

  • Tabs are now on top by default on Windows only – OSX and Linux will be changing when the theme has been modified to support the change.
  • On Windows Vista and Windows 7 the menu bar has been replaced with the Firefox button.
  • You can search for and switch to already open tabs in the Smart Location Bar
  • New Addons Manager and extension management API (UI will be changed before final release)
  • Significant API improvements are available for JS-ctypes, a foreign function interface for extensions.
  • The stop and reload buttons have been merged into a single button on Windows, Mac and Linux.
  • The Bookmarks Toolbar has been replaced with a Bookmarks Button by default (you can switch it back if you’d like).
  • Crash protection for Windows, Linux, and Mac when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins.
  • CSS Transitions are partially supported.
  • Full WebGL support is included but disabled by default at this time.
  • Core Animation rendering model for plugins on Mac OS X. Plugins which also support this rendering model can now draw faster and more efficiently.
  • Native support for the HD HTML5 WebM video format.
  • An experimental Direct2D rendering backend is available on Windows, turned off by default.
  • Web developers can use Websockets for a low complexity, low latency, bidirectional communications API.
  • Web developers can update the URL field without reloading the page using HTML History APIs.
  • More responsive page rendering using lazy frame construction.
  • Link history lookup is done asynchronously to provide better responsiveness during pageload.
  • CSS :visited selectors have been changed to block websites from being able to check a user’s browsing history.
  • New HTML5 parser.
  • Support for more HTML5 form controls.

Above is my screenshot from my attempt on the Mac. There are no add-ons that directly work with this beta besides Adblock Plus out of my many add-ons. It did seem to run off less RAM, seemed to be a bit faster than Firefox 3.6.6. And for that fancy looking UI upgrade, give it a try on Microsoft Windows Vista or Windows 7.
