After few hours of using Firefox, sometimes I could not play videos on any websites (such as Youtube, etc). Restarting Firefox or Windows could fix the issue, but then it randomly happen again and again after a long usage of Firefox for few hours.

Is there any idea to fix this problem?

Did you try this in Firefox Private Mode window to verify it's not a Addon caused issue.
