@CrispyRoll: You can prevent individual extensions from updating in pref.js. Type about:config in the address bar. You'll need to create a new boolean value in the form of extensions.{GUID}.update.enabled.

I use extensions.{582195F5-92E7-40a0-A127-DB71295901D7}.update.enabled to keep GMail Manager from updating.
