Firefox Community Forum

Videos on Bluesky have never appeared for me, instead they all say "Your browser does not support the video format. Please try a different browser." This seems to happen regardless of the video source.

Youtube isnt getting the video when using a non-private window. I've tried turning off every adblock I have. I removed some extensions that werent active in private windows to see if that was the problem. I tried closing and re-opening firefox. I restarted my computer. I logged out and back into google and then back out. Then i opened inspect element and the console and ... i have no idea what im looking at here but it says theres an error on the non-private window that *isnt* there on the private window, and it doesnt even show the playback element in the console as far as i know? i genuinely have no idea how to fix this or what is even broken, please help.

Since the latest update to my Firefox, videos (for example, in documents such as surveys) either do not load or they freeze. And in some streaming applications, either they play with no sound or when sound is turned on the video freezes. This was never a problem until recently. iMac desktop (2017) Ventura 13.7.4 Firefox 136.0.2 (64 bit) The same issue does not occur on Safari or on my iPad (using Firefox). Any advice?? Thanks.

I'm facing this problem of sound disappearance. I was casually browsing on YouTube when suddenly my sound went off. I thought maybe it was the internet but no everything was okay I also checked my speaker it was ok. Then I found out Firefox was unable to generate any sound. I tried to re-install but didn't work. Can you give me a solution?

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?
