Pictures and Movies do not display in Firefox 3

Hello!

I have a very big problem with Firefox 3.0
After an update 2.0 to 3.0 have this problem all the pictures and movies, My videos do not want to see displayed


I have the QT uninstalled and reinstalled, the Firefox, and Plugins installed solutions on the homepage of Firefox website but nothing helps?


For your advice I'm already grateful.

Adobe Flash Player even reinstall / update?

you either create a new profile or you can install the new.
