I can not play a cd or dvd since installing firefox.
My computer used to play a cd or dvd before installing Firefox but now it doesn't even recognize the cd. These are professionally produced cd's containing investment information (as oppose to some homemade cd) so I assume they are formatted correctly.

Thanks for responding back. You did not try what I asked you to. I am asking you to uninstall Firefox, play the CD and see if it works. If it does, we now know it's Firefox issue, if it does not work it could be something else.
