Firefox Support Forum

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.

Why is Firefox refusing to display Instagram videos?

Windows 7 Home Firefox 115.12.0esr (64-bit) Some Instagram videos play, most don't. E.g. https://www.instagram.com/reel/C8FM6cbOG7v/?mc_cid=e24e48195f

For a fraction of a second, the video shows what appears to be the initial display frame, then goes black. Audio plays. Displays OK on Chrome and Edge.

I've explored the following: Autoplay is allowed Turn off tracking protection Clear cache Clear cookies Digital Rights Management (DRM) is allowed Running in trouble shoot mode, i.e. no extensions Popups not blocked I do not have file user.js I tried hiding prefs.js. Hardware acceleration either on or off: no display

Is there a setting that tells Firefox to report why it makes its choices?

My Firefox browser kept freezing up and acting very slow so I closed it. When I reopened it all my tabs did not repopulate like normal. None of them. I have the box checked to reopen all tabs on restart and it has always worked, not this time. Why! How can I get them back. Thanks, Aldo
