Agreed, I have about 8GB of pages open right now not doing anything. Many computers don't have that much total ram. I think it's time to have per tab resource throttling. For example if a page uses over a certain amount of

. compute resources, the cpu cycles allowed in the next epoch are halved

. RAM it's memory accesses per second are halved in the next epoch

. network traffic it's kB/s are halved in the next epoch

This would allow all pages to still work but the resource intensive ones would be flagged quickly by users and developers.
