Maybe it's spurned on by the latest news about Opera's speed enhancements in Java or maybe it's just part of the general browser wars, but Mozilla's come out with Firefox 3.6 today and word on the street is this baby is fast.

What else is new?

Probably one change we've wanted to see is one-click theme swaps. These new theme types, Personas, allow users to preview new themes in a gallery, then click on it once and have the new theme applied. Of course, you have to install the Personas add-on and restart Firefox to make it work, but once you're there, you're gold. Now if they could just find a way to install and change add-ons without that annoying restart issue.

They've also added a right click option for when you're viewing videos to take them to full-screen mode easily and added some protections against out of date plug-ins. The notifications of these dated plug-ins will show up as a little bar across the top of your browser.

But according to Lifehacker, who've been testing since the alpha builds, the upgrade from 3.5.7 to 3.6 is deceptively low key. Apparently in page load time and in start-up time, the newest Firefox has cut their figures substantially, now ranking just a smidge slower than Google's Chrome stable release browser. (Chrome's development version still continues to rank fastest in testing.)

So what are you still reading this for? Go and get your new Firefox now.
