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?

All of a sudden, when I hover over a tab, a small window of the web site that tab is in, appears. Never happened before.

I did go into Performance Options - Visual Effects and unchecked "enable peek," but it didn't work.

How do I stop these windows from appearing?

Windows 10.

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
