It isn't possible for a normal user-level program like Firefox to prevent other programs from messing with its storage. Those programs would just modify whatever on-disk state necessary to install their plugins. The reason most browsers offer blessed ways to install plugins silently is because developers who are going to install plugins silently are going to do so one way or another. It's better to offer a maintainable, supportable, stable way than have developers hack something that doesn't really work.
