We've been keeping a close eye on the betas for the newest version of Firefox, from the first beta that got us excited to the most recent iterations that keep on improving. However, it seems it's not improving fast enough—Mozilla, originally planning for an official Firefox 4 release in late 2010, has now pushed the release date back to sometime in early 2011. So, if you're looking for a more stable (and add-on compatible) version of Firefox 4, complete with its speed improvements, UI redesign, HTML5 support, and other numerous improvements, you may have to wait a bit longer. Check out the Firefox 4 Beta Wiki for more info on the new release schedule.
