Firefox, a browser that literally saved the web from a monopoly disaster, is now available in its fourth avatar. Although in Beta 1, version 4.0 is reported to be quite stable. Among its new features the most important is probably the new sleeker look, somewhat similar to Google’s Chrome, only better. It also features a new Add-On Manager, support for WebM format (to let you watch open HD quality video), and a better privacy control.

Firefox 4 also has a new HTML 5 parser and provides a “full support for web video, audio, drag & drop, and file handling means Firefox 4 is ready to run the best web apps of both today and tomorrow.” Of course there is much more stuff packed under the hood, so you would probably need to download and take it for a test drive. Currently available only for Windows, Mac and Linux editions are coming soon.
