I'm amazed by how bad web browsers are at handling web pages requests for too much RAM. I have an html files with just a one-line JavaScript command to create a 1 GiB array, that I open a few tabs of, whenever I need to stress test a computer:

    var allocation = new Array(1073741824).fill(0);

It'd be useful to have a similar resource control in browsers. Maybe there is a way for an extension to achieve that? I'd be happy now if there was an easier way to find tabs consuming too much memory or cpu, like an alert or an icon.
