Firefox Support Forum

Hello, A few months ago, Firefox has not been loading Youtube videos properly. The video just never loads. Debugging steps I have done.

1) Disabled Hardware Acceleration 2) Deleted all cookies & cache 3) Ran Firefox in Troubleshoot Mode 4) Uninstalled Firefox & Reinstalled 5) Not a part of my debug but I recently did a fresh install of windows on my computer and installed Firefox with the same issue. I do get videos to work on both Edge and Chrome

I am at a loss at this point and any helping hints would be useful. I have an inkling that it might be put to my playback device but it wouldn't explain why it plays just fine on other browsers.

Any ideas?

I have searched for this problem, and only come across outdated information about Youtube's intentional changes to slowdown Edge and Firefox in 2019. This is not that.

When I load a new youtube video, the video will buffer as normal, and then buffering stops. Then there is a delay of about 10 seconds. You can see from my screenshot that the buffer is filled just fine, and playback begins about 10 seconds later. This also happens if I skip ahead/back or to any position in the video. This firefox install is on a new install of Windows 11, with a new xps 13. The previous xps 13 with windows 11 didn't have this problem, and I don't have this problem on my desktop setup with windows 10.

I use a few addons: decentraleyes, ublock, duckduckgo and I have privacy protections set to strict. I have tried a few troubleshooting steps and the problem persists. Things I have tried:

• safe-mode
• fresh install
• installed additional codecs
• used user-agent workarounds to show as a chromium based browser
• turned off hardware acceleration

The problem doesn't happen on chrome, but it does happen on Edge, which is strange. Because of this, I'm wondering if there is something going on with codecs. In the firefox screenshot posted, the codec used is vp09, same with Edge. But in Chrome the codec is av01.

I've lately noticed that when I watch some YouTube videos I get this white dot on the page for some reason, refreshing the page makes it disappear. What causes this?

Youtube rented video does not play after purchased. "Licensing error message" after hitting play button. Firefox 95.0b12 is supposed to work. Have latest updates... why won't it work? Seems Firefox/Modzilla not going to fix ongoing issue with rented Youtube/Netflix video rental problem. Is there a fix? Linux user.
