Firefox 3.5.1. has just been released to fix a potentially critical vulnerability. It’s not listed on the regular download page yet, but should be shortly.
A couple of days ago, proof-of-concept code was posted showing how a malicious web site could trigger a “drive-by download” when a page was viewed with Firefox 3.5. The 3.5.1 release plugs this hole.
You can get the latest version of Firefox from the Mozilla web site or by clicking on “Check for updates…” in the Firefox Help menu or you can wait for the update to be offered to you automatically when you launch Firefox. Personally, I wouldn’t wait too long.
