Well, not so long ago Mozilla released Firefox version 3.5.

I use Ubuntu 9.04 Jaunty, but I don't understand why I've not been asked to upgrade my Firefox (which is 3.0.11)!?

I can't press the "check for updates" button. Shouldn't it tell me it self? You know, I'd like to do update through the update manager instead of downloading a file and install a "new" Firefox version from Mozilla's homepage...
