Firefox Community Forum

For about two months, video quality has been persistently low for me on Youtube. Quality options are limited to 360p and I am unable to change it. Additionally, I am unable to play video on other platforms such as Vimeo, Pinterest and other streaming sites. Sites return errors such as 'Player is unable to play video at this time' or error code 102630. I have refreshed my cache and reinstalled Firefox and neither have resolved the issue. Notably, this issue does not occur on other browsers such as Chrome or Microsoft Edge. As far as I know my drivers are up to date and the Windows Media Feature Pack is installed, although it shouldn't be an issue seeing as sites work on other browsers. The issue also persists in troubleshooting mode. I've gone through the console and included images of some interesting errors that might be of use, although I don't have the technical knowledge to know what they mean. Please inform me if there is any other information I can provide that would help. Thank you!

Every time I use YouTube on Firefox it feels like a mental torture. It starts off with micro-stutters initially - annoying but nothing crazy. After some time the loading speed of the website and the videos themselves increase dramatically. And eventually it becomes unusable:

• Scrolling feels like the website is running at 30 fps
• The videos take several seconds to load
• It also takes multiple seconds to catch up when you select a specific moment of the video

The only solution so far has been restarting Firefox entirely, just close and open and pray. Then the problem comes back after some time.

Solutions I Tried:

• Disabling AdBlock (didn't work)
• Enabling Hardware Acceleration at all time (didn't work)
• Uninstalling unwanted Extenstions (didn't work)

All of these problems disappear when using Chrome or Edge.
