Firefox 144.0 on a W11 PC with all updates.

Firefox is running multiple (10-13) windows with 5-10 tabs each. Even if all Firefox windows are minimised and not being used, memory usage goes up all the time. It is currently, according to Task Manager, using over 5 GB of 32 GB of available memory. CPU is sitting at ~4%. Individual tabs, like Youtube watching CNN suddenly freeze and are no langer accessible and can't be unfrozen by anything I have tried. Even the mouse pointer is not displayed inside this tab I need to restart the entire PC several times a day only to have Firefox usable. I have turned off efficiency mode, but this did not change anything. I'll include a system snapshot with msinfo

Any ideas?

If you're able to get the browser to lock-up consistently when watching YouTube try launching the browser in troubleshoot mode and see if it also happens when running in that mode. That'll help to diagnose whether the problem is related to extensions or performance settings.

What a pity. I switched on the troubleshoot mode and let everything run as usual. Unfortunately, the same happed, as at 17:00 the memory that was gobbled up was at 7 GB again and the Youtube tab froze completely.

Any other ideas what I can try?
