Mozilla’s Firefox 3.6 is finally ready for download after months of testing.

The new edition of Firefox sports an array of features, least of which is an increase in speed — 20% faster than Firefox 3.5, according to Mozilla. It uses Gecko 1.9.2 web-rendering, which improves its load times, startup speed and stability. Javascript execution is faster and smoother as well.

The update upgrades Firefox to full HTML5 support and you get to install Personas – easy-to-use themes that let you personalize the look of your Firefox.
