Anybody has noticed that if you open the "About Mozilla Firefox" Window, the user agent for Firefox 3.0 is still set to 2.0.0.6? I don't know yet if it's the same thing for the desktop version.
This cause me a problem because one of my extensions, feedly, is running only for Firefox 3.0, and it seems they validate your version regarding the user agent.

Alive and kicking!
