There comes a time in the life of every piece of software where it simply must be retired in favor of newer versions. Such is the case with Firefox 3.6, as Mozilla has announced the venerable browser will be retired and anyone still using it will be auto-upgraded to version 12. Official support for Firefox 3.5 ended on April 24th while security updates stopped in January. Mozilla will upgrade any remaining 3.6 users in early May, although the company did not say exactly when. Still, you can always upgrade early to avoid any sudden shock. For those who like to be on the up and up, Mozilla announced the beta for Firefox 13 is now available, which brings with it a new home page, Google's SPDY protocol, and various other features. This is some good news with the bad, but really, people had to upgrade from Firefox 3.6 at some point.
