What is Firefox's support policy regarding end of life for prior versions?

more options

Is there an official policy on end of life/end of support for Firefox versions? The only source I have found is Wikipedia but I would like to be able to review Mozilla's policy as well as dates.

Wikipedia says 3.62 and 6.02 are the "current supported releases" but I cannot find this on Mozilla's sites.

This is the most official answer I have been able to find . . .

Old version Starting with the release of Firefox 5, the previous released version (e.g., Firefox 4) is no longer maintained and becomes obsolete. Since the release of Firefox 6, Firefox 5 is also no longer maintained; with the release of Firefox 7, Firefox 6 becomes obsolete, and so on. Although you can still download these old, obsolete Firefox versions, they contain security vulnerabilities and are unsafe browsers.

The EOL date for Firefox 3.6 hasn't been determined yet. The meeting about it has been postponed a few times.
