Plugin to automatically kill tabs that are stuck at 100% CPU usage (lemmy.ca)

So I regularly see issues in Firefox where pages from certain websites (Hello amazon.ca!) shoot to 100% CPU utilization and just never stop.

I'm wondering, is there a plugin that could periodically check the FF process list and identify tabs that are misbehaving like this (or in other ways, extreme memory consumption, perhaps?) and perform configurable actions like "Reload page (GET only of course) on tab" or "Kill tab" ?

It would be helpful because I see this issue on a daily basis, regularly to the point where these tabs are causing problems.

I already have "Auto tab discard" that discards unused tabs, but I'd like this as an extra feature, or a separate plugin.

Anyone who knows what could be useful?

This feels like a Band-Aid instead of fixing the root problem. I've never seen this happen, maybe you have a bad plugin causing it? Turn off all your plugins or start a new profile, then turn things on one at a time.

What is the root cause in your opinion, then?

To me, the root cause are sloppy web pages with JavaScript, and those ain't gonna fix themselves, so yeah, it's up to Firefox (if a plugin would exist for that) to do this
