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.
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.

about:processesCan you close tabs from there or just put them to sleep?
@l3ored you can close them with it. i find it useful for this purpose, though luckily i only rarely have the need. when you hover over any item listed in the table, at the rhs end a cross appears – click it to end that process, = close the relevant tab. you can sort the table columns by alphabet, memory, or cpu.
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.
from my experience things like this generally don’t work to well. The problem is that once its at 100% the sytem is bogged down so it won’t actually kill it till the tab has calmed down and you can interact yourself again. Granted it might still get it before it spikes again so im not saying its without merit. Just warning to temper expectaions if you do find something like that.
partner uses Vivaldi which has a very practical option to disable background synchronization for all sites and make exceptions for some.
i can’t see something similar in firefox/librewolf preferences
Good idea. For me it’s Google Drive and gmail.
