Behold the newest version of Firefox for Android, Firefox 4, or 4.0 if you prefer, a browser that Mozilla is saying is clocking in at three times the speed of Android’s stock browser. They say there’s JavaScript engine tweaks (this is what’d make it much faster,) tabbed browsing (I hope so!), Firefox Sync, and yes, add ons! They’ve added an official walkthrough video of the new features and we’ve got it for you here below – descend upon it while you download the massive 13MB file from the Android Market! Included in this new release is Firefox Sync, a sister that pulls all your desktop bookmarks, browsing history, open tabs, form data, and passwords to your mobile version, back to your desktop version, and back and forth again forever into infinity! This means you’ll only have to log into YouTube or Facebook in one place and you’ll be good to go anywhere you go! We’re happy there’s some HTML5 support in the mix, but sad to see a lack of Flash support
