Why is Firefox Suddenly Taking Over my CPU?
Today Firefox has suddenly started using ~20% of my CPU capacity, causing my cooling fan to run high most of the time. Since I had been running Firefox v.149.latest, I tried updating to v.150.0, but that made no difference.
It's not Firefox by itself (only Task Manager open) but whenever I open another tab with almost any website (including this one) that CPU usage spikes. What gives?!
Details: Running under Windows 10 Pro (yes, I have installed the ESU package, good until thi8s fall) on a Lenovo P1 Gen 2. Currently running Firefox inside a Sandboxie Pro v1.17.4 sandbox.
Please Help! -- jclarkw

I'm now running Firefox outside the sandbox, and almost everything I said above is still true except that this site no longer hogs CPI. Most others still do.
Since I'm now outside the sandbox, I can probably "Send Data," but that option seems not to show up in a reply...

Is nobody else seeing this problem? Or are no solutions available? -- jclarkw
I'm having the same problem, but only when playing YouTube videos. Checking in task manager show one Firefox process showing very high usage. It does sometime goes down after a while.
For solution to this problem, see https://support.mozilla.org/en-US/questions/1578564#answer-1816178
Finding the offending add-on was not as easy as it seems. Perhaps time is required for some of these extensions to get triggered and cause trouble? -- jclarkw
