'''bold text'''After waking up to no sound, I updated firefox, to no avail. Not only do I not have sound on fb or ig youtube, they all work on other browsers. Again, it has been updated, can't find a setting anywhere, just no sound from anything related to this browser. Please respond asap or I will switch for good. I don't want to, as I have many things saved here, & a good workflow, but...unacceptable I can't contact anyone about this either. Not ok. Please advise.
