Mozilla has slowly been cutting off updates to Firefox 1.5 and that is very obvious in the last update (1.5.0.11, in which all that was included was a patch for the browser's FTP protocol.)
This decision could be a bit rash, because many users and especially businesses still use 1.5 and like to test the stability of an updated browser before upgrading.
I will still be using 1.5 as I feel 2.0 is bloatware.
