I am facing this error message while streaming videos. But it doesn't appear in every video, just on some few websites. Things I have tried so far: clearing cache & cookies but failed reinstalled firefox but failed disabled add ons, even started firefox in safe mode but failed reinstalled windows a few days ago but still same.

I have tried using different browsers such as chrome, opera, edge and it works fine in all of them. Is there any solution for this issue?
