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.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.


For more information about Firefox's processes, check out Firefox's "about:processes" page. It will show you which sites are loaded in which processes, how many threads and how much memory each process is using, and a button to kill a process.

I am missing this process names a lot. Thanks for submitting.
