Grown tired of your current browser? You may want to consider giving Firefox 3.6 a try now that the open-source browser has been made available in Release Candidate form. And if you're worried about being left behind with an unfinished product, don't be.
"[Firefox 3.6 RC1] may update itself periodically and will eventually be identical to the final release," Mozilla stated in the RC's release notes.
The latest release is built on Mozilla's Gecko 1.9.2 engine, which the company says has been under development for several months and includes a bunch of improvements, primarily for Web developers. It includes over 70 fixes from the last beta to improve performance, stability, and security features, and has the ability to run scripts asynchronously to speed up page load times.
