Mozilla Firefox 4 - faster, more secure, easier to use and sporting a new look


New In Firefox 4.0: 

  • 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.
