I have been using Firefox for many years now and I have always been greatly satisfied with its stability, performance and features. However with the last couple of releases something has changed. The number of tabs I keep open and what they are connected to have changed very little over the years. The CPU utilization has never been much but now it has become huge - utilizing multiple CPU cores and running them at 100% whether I am using the browser or not. I have gone thru each individual tab/web page removing it, waiting for a period of time and them re-adding it assuming this was a website coding issue. Nothing changed. So I gave up and move 98% of my web browsing to another browser (Opera) - moving one website at a time until what was left on Firefox was 11 tabs. Finally the CPU utilization went away. I got the latest Firefox version update today, installed it and now Firefox has changed behavior yet again. Those same 11 tabs will not use any CPU as long as I keep Firefox open and visible on screen, but if I minimize the Firefox window it immediately jumps up in CPU utilization. This makes no sense to me.
What adds to all this frustration is I am running on a system76 Thelio desktop. While extremely fast they have a known issue with their somewhat loud CPU cooling fan kicking in too fast when high CPU utilization occurs. Firefox never used to cause the fans to run but now the latest couple of versions cause the fan to run continuously.
Here is a paste from "top" showing the top 2 cpu processes - both from Firefox and the browser is minimized:

My apologies if I have run on with too much info that is of no help. If anyone has any ideas it would be appreciated and I would be happy to test. FYI, my OS is up to date, Firefox is up to date, BIOS is up to date, I have restarted Firefox many times and I have rebooted several times. I thought Mint might be the issue so I loaded Pop-Os and tried it with the same results. Btw neither Opera or Brave shows the problem. However I would prefer to use Firefox as I really like the features - especially how it handles tabs and grouping them.
Thanks in advance for any help!
