quote:Taras recently blogged on how websites manage to ruin Firefox performance by continuing to do something even though their tab is no longer active they keep updating the view that you cannot see. He wondered whether it would be possible to suspend these tabs from an extension. I looked into this and there is a way to suspend all timeouts for a tab something that an extension could use. Getting the details right wasnt quite trivial but I think that my extension gets it right now: Suspend background tabs. Enjoy!
This doesnt completely disable all activity in the background tabs of course. Network requests will continue, videos will also keep playing. So I might implement some improvements in future. However, please have understanding that this is a very low priority side-project for me. So its best if you bring your code. The current code is here.
