Firefox Community Forum

For the last two years the issues with video stutter have been worse and worse for me. I don't know if it is because of a different codec the video is using, but if it was I would expect the fans to ramp up from trying to decode it. Instead, my laptop stays always silent, but the video laggs like crazy when I want to play it at native 1440p.

I cannot view or change the video codec, since the current issue happens on a platform (herohero.com) other than youtube.

Whenever I play videos on YouTube in Firefox, the video is always choppy and does not run smoothly. I’ve tried restarting the browser and checking my internet connection, but the issue continues. This problem only happens in Firefox, not in other browsers.

Hello Mozilla Support Team,

from yesterday playback speed on youtube is not working. When I open the same video with Edge playback speed is available.

Could you please check and rework?

Thanks in advance.

Many greetings Stefan

When I am watching a YouTube video and switch tabs, sometimes, on return to the YouTube tab, I have no sound. It is not muted. The system sound is fine. This does not always happen. I can switch tabs and still hear the sound. Then switch back and no sound. The video is not paused. I've tried pausing and playing the video, still no sound. Refreshing the tab doesn't help Where do I go to turn the sound back on? Win11, Firefox v144.02 64 bit.

I just switched to a new PC (Windows 11) and when using Firefox to watch videos, the audio fades in briefly instead of starting instantly. This happens with youtube, prime video, netflix etc. I have tested in Edge and this does not occur. I am using a bluetooth headset. I haven't been able to find anything about this online so open to any help.

Trying to run Prime and Netflix in a Linux browser on my new Lenovo Chromebook Plus 14. Not that this is an ARM based unit (Kompanio Ultra 910).

I can successfully download Firefox for Linux: Mozilla Firefox Debian Package mozilla-deb-1.0 144.0 (aarch64)

But when I go to run streaming video services get: Prime Video is incompatible with your current operating system or web browser. You must update to watch Prime Video titles. Review the Prime Video system requirements. If the problem continues, please contact Amazon Customer Service and refer to error 7132.

Same with Netflix.

any ideas, thoughts, solutions?  :)

Cheers.

I need assistance resolving an issue where videos on YouTube play choppily in Firefox. The playback stutters frequently, even at lower resolutions, while other browsers stream smoothly. I’d appreciate guidance on troubleshooting steps to improve video performance—such as checking hardware acceleration, browser settings, or possible extensions causing the issue.

So Im currently trying to watch young sheldon on netflix, and im doing it through firefox, and it wont work, it says error code f7701-1003, thank you for your time.
