Last week a rather sketchy, buggy version of the Firefox 4 beta was found floating around online and many reported a number of issues. However, it looks like Mozilla has gone ahead and released a newer official beta of Firefox 4.0 that includes a number of new features posted below. Future updates to Firefox 4 are said to include speed improvements and bookmark, passwords, and settings syncing functionality across all Firefox supported devices.

Unfortunately the new UI with Chrome style tabs and other visual improvements is currently not available for Linux and Mac versions of the beta.

You can download the official Firefox 4.0 beta for Mac, Linux, or Windows from Mozilla here. Let us and the rest of the BlogsDNA community if you find anything interesting in this latest beta release.

New Features in 4.0:

-Updated User Interface with Tabs on top (Google Chrome style)

-New Add-ons manager

- HD quality  WebM video support

-Improved HTML 5, Privacy, and CSS support.
