Mozilla is cranking out new versions of Firefox like its coming out of a copy machine. It seems like it every two weeks, a new version of Firefox comes out. Speaking of the devil, Firefox 6 is now out.
You won’t see anything different because there are no UI changes, but it will be 20% faster. So they say. Firefox 6 is available on PC, Mac and Linux. As of this writing, Mozilla’s website still displays Firefox 5. You may have to wait a couple of hours until the official announcement.
If you’re an Ubuntu user, just follow the instructions I wrote here for Firefox 5. This will work with future versions as well. By the way, I just tried. It’s not quite there yet. Just wait a couple of hours until the ppa repository is updated.
