Whenever I try to watch a video on YouTube since the latest firefox update my browser hangs. I thought it might have been the latest flash update but YouTube still work in all of my other browsers just fine.

Hi,

Please try to Delete all the existing Flash cache in the Windows Control Panel > Flash Player > Advanced as well as Clear Now the Cache, Cookies, and Site Preferences in Firefox Tools (Alt + T) > Clear Recent History.

You may also have to fully re-trust Firefox + its processes/files in all the configuration areas/modules of any and all security software (antivirus, firewall). Please see this.

AV/Firewalls Configuration

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.

Thank you - I thought it was the old problem with Flash Player 11 in a new disguise, but opting out of the HTML5 trial sorted it for me.
