Mozilla today released the Firefox 3.5 beta 4 which will be the last beta before the final version of Firefox 3.5 is out.

The latest modification to the browser involves the addition of restore closed tabs and windows or undo the “close window”. Codename Shiretoko will allow users to open the last three closed tabs and windows in its default configuration. Opening recently closed tabs and windows is an option that Mozilla has built into the History menu.

The beta also refines support for HTML5 offline mode, the W3C Geolocation API, JavaScript query selectors, as well as CSS properties.Private Browsing Mode has been tweaked, and there’s now broader support for new web technologies such as Ogg file formats, which allow videos to run within the browser without needing to install codecs.This release is considered to be stable, and is intended for developers and members of testing community.

Mean while Mozilla released Firefox 3.0.10, just six days after the  release of Firefox 3.0.9, emergence of yet another update is for  fixing a major stability issue and one security fix
