The popular internet browsers gets a face-lit, HTML 5 features, updated rendering engine.
The battle for web browser supremacy takes another turn with a new contender on the block: Mozilla Firefox 4. On Tuesday, Mozilla released the first beta for the new version of the popular open-source internet browser. Firefox 4 Beta 1 packs in a gamut of features that should bring it back up-to speed with the rest of the pack.
Mozilla has taken a lot of inspiration in terms of design for its new browser: the UI has received a complete makeover with Chrome-like tabs-on-top, and a combined single button access to all the toolbar options ala Opera 10.50+. The developers have also updated rendering engine to Gecko 2.0, revamped the Addons Manager to provide extra space and additional tools (again, very much like Chrome), a new HTML 5 engine with WebM video support, new crash protection system, and host of other features for third-party developers. Full list of changes below.
