Firefox "Not Responding" on YouTube Suddenly

As of yesterday Firefox is no longer loading YouTube videos properly. When I go to YouTube (any video) nothing happens for about 5-10 seconds, then Firefox is "not responding" for another 5 seconds, then it resumes. The video does not automatically start to play, I have to click it to start. It never did this before.

I think it might have been because of a Flash update so I've tried multiple previous versions and it's still not fixing the problem.

Any help would be greatly appreciated, I've already spent a good 5 hours on this.

Hi,

Please try to Delete all the existing Flash cache in the Windows Control Panel > Flash Player > Advanced. If the problem persists, you can also try the IE Tab + or the IE Tab add-on to temporarily watch problematic Flash content inside Firefox.

I'm using Windows 7 - I do not see Flash Player in the control panel. Do you know the path for Windows 7?

I deleted the cache via this folder path: %appdata%\Adobe\Flash Player

Didn't have any effect.

If Flash player settings manager is missing then probably the installation is incomplete. You can try a clean uninstall and install it afresh.

Flash 10.3 r183 doesn't use the control Panel to access the Flash settings, so with that version you need the website based setting pages.

Flash Website Storage Settings panel:
