I thought I would report that after updating Firefox to version 149.0, I had no audio initially in YouTube videos but before I had NO problem with any. For a Firefox video sound example, the video played audio fine at: [https://www.youtube.com/watch?v=LtOGa5M8AuU]. My computer audio worked fine in Windows System. I did not change any YouTube audio setting in the videos. Audio is not blocked. After clicking on more videos and trying to play them, the audio is now getting back to the way it used to work although the audio setting are still the same. This is really weird and has wasted some of my time. Also, after the Firefox update, now I cannot drag and drop a URL into a Bookmarks folder from the URL bar or whatever it's called after doing a Search with DuckDuckGo or with Google with the "Search and turn off Show search terms in the address bar on results pages option" turned off! I did not change any setting in Firefox to cause this issue. I now wish I had not have updated Firefox! Please resolve dragging URL issue and hopefully whatever caused the audio problem will not occur again.
