Firefox won't let me watch videos anymore

[RedRobin]

I uninstalled and reinstalled Firefox and updated Java and that didn't help, any other suggestions? I'm jonesing for YouTube so please help!

Re-install the latest version of Adobe Flash player. Java doesn't have anything to do with the majority of videos that play inside your browser.

Please specify your Firefox and Flash version because If you are using Flash 11.3 and RealPlayer then Flash videos or games may appear black or never play. Hence if you are facing problem due to this reason then you will need to uninstall Flash 11.3 and install a downgrade version of Flash 10.3.
