Firefox Community Forum

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.

About two or three times a month the PC randomly freezes completely if a video is running in the actual Firefox browser (regardless of the site, regardless of whether it is in the active tab or in the background). First the image freezes, after about 10 seconds the sound freezes. Only a hard reset helps. The problem is observed both in actual Windows 11 and in Manjaro Linux. In games, rendering, stress tests and other PC works stably, does not freeze. How to solve this problem?

1. Close Firefox (FF) with some tabs open 2. While FF is closed the websites are updated 3. Open Firefox, tabs reopen 4. Go to tabs

Expected: Tabs should the latest version of the website (ie the page has been refreshed)

Actual: Tabs are showing the old, previous (cached) versions of the website and not refreshing to show the latest

User has to manuall refresh each tab to see the latest version of the page
