Hi,

I've been trying to solve this issue for the past several months with no avail. I tried configuring some settings via about:config with:

gfx.webrender.compositor - false widget.windows.window_occlusion_tracking.enabled - false

I also unchecked both "Use hardware acceleration when available" and the "use recommended performance setting".

Essentially, I want to be able to watch movies/videos on sites like Netflix and Hulu. Right now only a black screen shows with the audio playing or the screen is frozen in one scene and the audio continues playing.

Does anyone know what else I can do to solve this problem?

I don't know when it began but on 136.0.3, I'm experiencing choppy playback of 4k/24fps video. 60fps works fine, as do lower resolutions of 24fps content. I confirmed that YT is using the VP09 for playback.

No matter what site I am using, youtube, or any other site that contains videos or audios, I cannot hear the sound when using Mozilla. I want to mention that there is no problem with my speakers because if I use Chrome on the same computer, the sound works. Can you help me?

Videos over a certain resolution won't play on Twitter/X. Anything 1080 and over vertical won't play. I get audio, but not video. If I use Maxthon (Chrome) I can see the video. I've downloaded the video files and those that are 1080 vertical are the ones that won't play in Firefox. In the picture I'm sending, you can see that Firefox is stuck on the very beginning of the video and the Maxthon video has started, hence the subtitles. Is there a setting in Firefox that will allow me to watch these videos? Thank you.

I've recently switched back to Mozilla Firefox again & I installed it via its official installer in Windows 11.

There's something wrong with playback what I noticed is that if I disconnect my wired earphones/headphones & then it pauses the media playback.

I am not aware that if this is an issue, bug or default behavior.

If it is not an issue then is there any possible way to modify such behavior.

Note:

• This thing is tested when all extensions are turned off (disabled)
• Such behavior is observed in both web players such as YouTube, dailymotion, etc. & locally stored/saved/downloaded videos played in Mozilla firefox.
• Not any setting was imported from any browser
