I am also disappointed in the Mozilla developers for forcing features on to their users. They removed the old FireFox theme instead of just adding a new one (the users had to recreate the old theme), they have a built in virus scanner which I don't think can be disabled, and users can't copy and paste links into the "browse" textbox on websites like imageshack. They should be enabled by default; however, there should be options to disable features I don't want. Especially if they weren't even included in FireFox 2.
