I have tabs that I can see using resources in the about:processes view but the value in the name field is something like "Firefox (8748)" or "https://fooSite.com". If I have a lot of tabs open, which I always do, it's not clear which one is causing the issue. It would be great if there was a way to show the url that is loaded so that one can quickly choose to stop it, reload it, or close it. Yes, the X action sort of let's you do that but you still don't know exactly which tab you are xing and it's only a kill switch for the tab in the end; there's no choice to resolve the issue by just reloading the page in the event of some video element that is consuming gpu for some reason. It might be a tab that I want to keep around. Making a little more meta data available so that a user can easily track down the specific tab would be great. Imagine I have 70 windows open... Yes, probably a corner case but it's the way I roll.
