Firefox 4 beta is now available for download and it features a new user interface, multitouch support for Windows 7, improvement in protecting your privacy, support for HTML5 video standards and WebM format, 3D graphic rendering with WebGL, Audio API, crash protection and more.
In addition to the above mentioned features, users should expect a much faster start up time, page-load as well as huge performance enhancements, thanks to the inclusion of their brand new JägerMonkey JavaScript engine.
Firefox 4 beta also comes with Feedback Add-on (in the upper right corner) to encourage users to submit their feedback to Mozilla for further improvement. If you have it installed on your computer, like it or hate it, please let them know.
We tried to install it on our Mac but it seems that a lot of add-on are not supported at the moment – will wait till the release of the final version then.
In our brief tests, the Flash performance in Firefox 4 Beta 10 appears to have improved in Mac OS X. Video plays better and consumes fewer resources. Likewise, most of our add-ons and plugins were compatible with this release.
Loading Facebook.com is about 1 second faster than Google Chrome. The memory usage is well kept under 300MB, while Google Chrome is a memory monster! I like Firefox 4 and I will try it for a longer time to see if Firefox will return to be my permanent default browser or not.
