Firefox has a decent task manager view that I use to identify rogue tabs like that. Shift+Esc -> sort tabs by CPU usage (it lives at the URL about:processes and can be found under 'More tools' -> 'Task manager' too). I imagine that's how you discovered it was LinkedIn? Though if you're not a tab hoarder it might be fairly easy to discover just by trial and error...

I kill LinkedIn tabs via task manager all the time. Yes, that is how I had figured out that it’s the culprit in almost 100% of the cases. In fact just killing the tab and refreshing/reloading it helps, when I need that tab.
