Mozilla for some time after switching to the rapid release process talked about releasing Extended Support Releases that would give companies and organizations some breathing space in the race to test and deploy new browser versions. With the first ESR release (which will be Firefox 10), comes the Firefox 3.6 end of life announcement. Firefox 3.6 users will receive update notifications in April to update the browser to the latest stable version by then.
