The countdown to Firefox 2 marches on with the release of Firefox 2 Release Candidate 2 this weekend. If you had RC1 and have automatic updates turned on, you've probably already been notified of the new version and have it installed already. If not, now's the perfect time to download RC2 from Mozilla.com. The changes in this release are almost exclusively behind-the-scenes security, performance, and stability fixes, so don't expect anything mind-boggling if you've been using RC1.
