Okay, that fixed it, thank you . . . I forced an update Firefox Add Ons (even though I had auto update enabled), and now I have version 7.2.76 and everything is back, I’m happy 
February’s 7.2.75 wasn’t working, but 76 does.
I finally found that my Ad blocker was blocking it for some reason, it never has blocked it until now. I just had to change my Ad blocker setting to allow BTTV and it worked. Check your ad blockers.
As an update, Chrome published our extension update this morning. If you are still having issues with Chrome, be sure to update the extension to version 7.2.76.
