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.
