Closed tabs still consuming CPU

I have been experiencing issues of extreme CPU consumption.

When I look at Task Manager, I see tabs consuming resources - tabs I have closed.

See attached open tabs screen shot, and task manager screen shot. The Register (tech website) is clearly consuming CPU and memory, even though I closed that tab yesterday. WTF is going on?

Linux Mint 22.1 Cinnamon Cinnamon 6.8.0-90-generic

Firefox is installed from the package manager, not as a flatpack.

Extensions: Privacy Badger, and uBlock Origin are installed and active on most tabs. (YouTube has become temperamental about privacy extensions, and a few other Google-related sites as well) CookieAutoDelete - though that just deletes cookies/sites data some seconds after a tab is closed.

The Register example is just for reference. The service that seems to consume large quantities of CPU, even after I close all related tabs is YouTube. It has on occasion made the system crash.

That icon indicates it's an utility process and it refers to a subframe, not a tab. Perhaps one of your open tabs has a subframe with something from The Register.
