Firefox 3.5.1 was released on the 16th of July. It fixes a serious security problem. See here for details:http://www.mozilla.org/security/known-vulnerabilities/firefox35.html#firefox3.5.1
Vector builds for both 5.9 and 6.0 are now available. I've got strictly limited access for the next 48 hours or so, so there has not been an announcement for either of these builds yet, but both Firefox and language packs are available now. Hopefully I may have time to catch up with some of the backlog of repo maintenance early next week, and will make proper announcements then.
