I had flash player 9 and flash player 10 in firefox. Flash player 9 would only play the last few seconds of a clip and flash player 10 would not even show up. I located libswfdecmozilla.so and did "sudo rm" on it and it was removed after prompting me for my password. After that I could no longer see flash player 9 in my fire fox add ons and flash player 10 worked fine.
