Firefox upgrading everybody, you have no choice now

Firefox 12 was released this past month and a new feature is one that automatically upgrades the browser to the newest version when available.  For old users of Firefox 3.6, you had to manually upgrade the browser.  It did not alert you to a newer version being available.  The result is millions of users still using the outdated browser version 3.6.  Mozilla will give Firefox 3.6 the coup de grace next month by automatically upgrading users of that 2010 browser to Firefox 12.  

Mozilla issued its final security update for Firefox 3.6 on Jan. 31, and officially retired the browser from support last Tuesday, April 24.

Mozilla has given Firefox 3.6 users plenty of warning, telling them several times over the last months that they need to upgrade because of the impending retirement. The newest such message told Firefox 3.6 users that it was their last warning before Mozilla switched on automatic upgrading.  If users want to keep Firefox 3.6, they must disable updates before the May auto-upgrade. On Windows, that setting is reached by selecting "Options" from the Tools menu, clicking the "Advanced" tab, and then clearinng the box marked "Firefox" under the heading "Automatically check for updates." On the Mac, the same dialog can be brought up by selecting "Preferences" from the Firefox menu.  But why would you want to do this?  Just upgrade now.
