There are only 2 currently updated and supported '''''Released''''' versions, Firefox 9.0.1 and Firefox 3.6.25. Support for the Firefox 3.6.x versions is likely to be discontinued in the first quarter of 2012. *There are also the Beta (final public testing) and Aurora (initial public testing) versions. *Firefox 10 (currently Beta), will replace Firefox 9.0.1 at the end of January 2012 and Firefox 11 (currently Aurora) will be transferred to Beta). *New version '''''Releases''''' occur every 6 weeks and the new Release version always replaces the prior version, and the prior version is abandoned as to security and stability updates. Near the same time, the Aurora version is moved to Beta and the Nightly (very experienced testers only) is moved to Aurora. *Current '''''Release''''' version download: https://www.mozilla.org/en-US/firefox/all.html *Other supported version: https://www.mozilla.org/en-US/firefox/all-older.html For Enterprise '''''only''''': *https://wiki.mozilla.org/Enterprise/Firefox/ExtendedSupport:Proposal *'''''NEW''''' --> https://blog.mozilla.com/blog/2012/01/10/delivering-a-mozilla-firefox-extended-support-release/ *https://wiki.mozilla.org/Enterprise '''If this reply solves your problem, please click "Solved It" next to this reply when <u>signed-in</u> to the forum.''' ------------------------- Not related to your question, but...
