Hello,
As title says but only happens in Firefox. Chrome and Brave browser playing same content without an issue so it is not network related.
If video is 60fps 720p or 30fps 1080p Firefox plays without a problem.
Win11 on same computer plays all 60fps content with Firefox without a problem.
Anyone got an idea how to fix this? I really don’t want to switch browser just for this issue.
Edit: OK, I think it is all about codecs Firefox is using. So somehow I have to change them.
Any ideas are welcome.
Things I’ve tried:
- Disabled / Enabled all Firefox plugins.
- Disabled / Enabled Firefox hardware acceleration.
