Firefox 3.6.16 and 3.5.18 security updates released as Firefox 4 launches

firefoxJust because the shiny, new Firefox 4 is now ready for downloading by the general public doesn't mean Mozilla is turning its back on users who can't (or don't want to) upgrade. Security is a big priority, and 3.X users will continue to see patches for quite some time.

In fact, both Firefox 3.6 and 3.5 received security updates in tandem with the Firefox 4 release. The new versions blacklist a handful of invalid HTTPS certificates which were issued by Comodo.

Firefox's internal update mechanism should take care of the process for you, but you can always give it a push by clicking Help > Check for Updates. Mozilla does urge users to upgrade to Firefox 4, and there's really no reason not to. If you're ready to make the move, just visit and you'll be offered the correct version for your operating system.
