Hello I am running 115.12.0 Firefox ESR June 11, 2024 release 64 bit on Windows 7 Professional 64bit. Which I still have to use till I can afford a new PC in a few months. When I have a streaming youtube music link open when I try to open another tab the Music Stops playing and Video Freezes and cant have the audio in the background continue. I have tried several Add-on's that are suppose to fix it they do not work. Have also tried the following about:config edits '''widget.windows.window_occlusion_tracking.enabled''' set to '''false ''' and '''media.block-autoplay-until-in-foreground '''set to '''false ''' Before these would fix the issue till the update to the above update now they no longer work. Have also tried using the '''Troubleshoot Mode ''' which makes no difference.
