Why don't embedded YouTube videos play in Firefox?

I have recently noticed that embedded YouTube videos do not play in Firefox. When you click on the video it says "An error has occurred, please try again later". The video will play in YouTube if you open in a new page. They also play in other browsers like Safari.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems

I tired all of that and still no help. I have asked friends to try this on their Firefox and it works so not sure what is wrong with my settings. Any other suggestions?

seemed to fix it for me, once i started up in " safe mode" so thanks i'm glad it solved it, also i removed a yt downloader i installed recently which also might have caused the problem since it was inconcurance in time the problem started, i got an 10.5.8 and the ad on might have been banging things up.

Thanks. Thanks a lot.
