Try to restart the computer and see if the issues still continues or not.

Hi Travis, what happens when you try to play video? Is there any error message, or it just seems to buffer, etc.?

It is hard to know what could have changed. Possibly Firefox was displaying some kind of permission request on a Peacock page and it was denied by a pawpress?

When you are on a site, an icon of two lines with little circles appears next to the lock if you have customized permissions for the site. Do you see that one? Or you may also see the autoplay icon there, but of course if you are clicking the play button yourself, the autoplay block isn't very relevant.
