Mozilla has released the beta 9 version of Firefox 4, bringing them closer to a release candidate and final version release in February 2011. Mozilla has been working on Firefox 4 for quite some time now and the numerous delays have been costing them.
Mozilla has also added support for 7 new languages for Firefox 4 taking the total supported languages to 76. To view the complete list of changes visit this page. You can download Firefox 4 Beta 9 from here or visit this post to learn what has changed in this beta.
Firefox has been losing market share in the past few months because Google Chrome is stealing their thunder. However, the good news for Mozilla is that Firefox just became the most used browser in European countries. Hopefully the release of Firefox 4 might turn things around for Mozilla.
