Diagnose CPU consumption
Once in a while I see one of my CPU cores 100% utilized. Checking process list reveals Firefox. This state persists until I open the Firefox Task Manager. The CPU utilization instantly drops to few percent.
Any idea how I can diagnose what causes this CPU utilization?
Note: `perf` says the Web Content thread is 100% utilized. But the call stack gives no obvious hints about the reason.

Hello wirch.eduard ,
Three things you could do :
- Read this article : https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources
- Type in the address bar : about:performance
- Type in the address bar : about:memory
I hope that gives you enough information (?)
