Currently if you look in Windows 10's Task Manager you'll see a bunch of "Firefox" named processes. My suggestion is to add a distinct ending string to describe what each process is for/doing. Often it seems a process is doing lots of work for a particular URL/tab. I'd like to be able to see which tab or add-on is doing work outside the Firefox Task Manager. It is a fine new feature, but it can be useful to have multiple ways to find information (and verify it). Ideas for names include... group shared work into a category (video playback, encryption, etc) use the whole URL for the process name, since it's held in a tree structure under Firefox and has an icon to match. On Linux they'd see the parent PID. or more complex... if domains are unique for tabs, that's an obvious label if many tabs share the same domain then folder/file endings might differ or the "title" the web page itself sets could differ If they change often this might add a good deal of extra work, so I understand if it's a feature that's disabled while on battery. But for debugging or profiling it might be a handy way to estimate for regular home users.
