YouTube videos are frequently buffering and sometimes play slowly in Firefox, even when my internet connection seems to be working normally. Please help me identify the cause and suggest steps to fix the problem. I would also like to know whether any Firefox settings, extensions, cache, or hardware-acceleration settings could be causing this issue.

FF dev 155.0b5 (but this has been ongoing for 1+yr). W11p. Is there somewhere in settings where I can "disable" whatever is blocking videos from being seen? (for example BBC news videos). I have to go to troubleshoot mode to watch. I have previously disabled all potential blocking exts like ghostery & UBlock, but to no effect (still no videos). I have looked in security in settings. Otherwise, I either go to troubleshoot or open chrome. Or, is there an extension that will allow that video viewing? Please advise, thank you.

It was working fine until the day before yesterday. The volume of the speaker got low before it stopped working. The PodCast and Vimeo are working fine. So it is not the problem of my computer speaker.

When using Firefox to access Netflix the video is distorted/greyed out in HDR mode, but displays properly using Microsoft Edge. None of my other streaming services experience this issue. How do I get Firefox to properly display Netflix in HDR mode?

Netflix customer service sent me here.

When I play YouTube videos in Firefox for Android, the video keeps pausing and buffering constantly. I have tried clearing browser cache and disabling all extensions, but the problem still occurs. My device is Android mobile phone. I hope to get help to fix this playback stuttering issue.

My computer just updated Firefox. Since that happened I can't stream a movie in full screen. That is, I can make the window as big as the screen, but I can't hide the tabs, time and date, pull down menu titles, etc, I want to see nothing but the movie. On Netflix you typically do this by clicking on the rectangle in the bottom right corner. But now nothing happens when I click on this. Can you help with this?

Thank you

I uploaded an image to show what I mean, but nothing is showing next to the words Uploaded images.

Los videos de YouTube no se reproducen correctamente en Firefox. Algunos videos no cargan o se quedan congelados y no puedo verlos normalmente. Ya intenté actualizar la página, pero el problema continúa. Quisiera saber cómo puedo solucionarlo.

Title pretty much says it all. got the new update and now every time i watch a video on Disney +, the pause menu will fade then the video goes super dark. it was working fine yesterday

Hello Firefox support. I'm having trouble joining meetings in calling applications where I stream my screen from my laptop. I tried several different applications on my Windows 10, and unfortunately, in the Firefox browser, the audio doesn't work at all in various different applications, which reveals that the problem isn't the app. I couldn't find help in Mozilla support, so I'd like to know how I can stream my screen (either full screen or in browser, etc.) along with the audio so that everyone in the meeting can hear the sound of my computer. Thank you.

Hey. Something happen after the last update of the browser. I can se videos online but not hear any sound . I have tried with other browser then i have sound but in firefox i dont have sound . Is this fixable  ???? Kindest gregards Tom

I'm on a Mac desktop, Mac Tahoe 26.6.2, using the latest version of Firefox, although this frequently happened in previous versions. Audio often disappears from videos and reels. When I refresh the page, nothing happens. To get sounds working again, I have to quit Firefox and restart, but by then I've lost the reels I was watching. This is a big issue for me as I am a musician. Any ideas on how to fix this permanently?
