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 is an interesting idea but Firefox itself should both limit resource consumption and do those sorts of stops. Hmm.

    You'd think it would, and it somewhat checks when a page becomes unresponsive, but that's it

    Amazon pages (yeah, Amazon sucks, I know) typically just start normal and jump into 100% CPU after being open and left alone for an hour, and Firefox is all okay with that.

    I'm not

    this. no tab should be able to use more than like 10% cpu without a popup and the user manually enabling a higher level from a dropdown or something.

    I'd change that to "more than 10% continuously" because any page can shoot to 100% in short bursts for a wide variety of valid reasons.

    It's the continuous load that is a problem, so basically 100% for 10 seconds straight would be a problem

    see thats the problem. once it has 100% if it don't let it go then anything setup to stop it can't function. You have to have reserve. I mean you could do 90% maybe even 99% but honestly the issue there is it shoots up so fast the stop does not get a chance to launch.
