Firefox & a very strange bug

I have strange bug in firefox here, after saving some images to a floppy, firefox ALLWAYS says "no disk inserted into drive A:; Abort, Retry, Ignore"(Or something like that, i get the german error message since this is a german pc, but you know what i mean) when i try to save something. pressing any of the above leads to a repeat of the message. if i click it often enough away, it stops and my file is saved, but it's still stupid and comes back everytime is try to save something. somebody got a idea how to get rid of that bug?

Or go into your hardware profile and disable the drivers.
