The next major update of Mozilla's popular open source browser Firefox is due by the end of this year but enthusiasts and developers don't have to wait to see what goodies it brings as the first Firefox 4 beta has now been made available and is awaiting testing.
According to its maker, Firefox 4 comes with a refreshed interface on Windows - tabs on top plus a Firefox button that replaces the menu bar (BEd: Opera has something like that too, since v10.50), a new Addons Manager and extension management API, support for the WebM video format and more:
- 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.
- 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.
