I just run into this issue while investigating why Firefox suddenly stopped opening any page (clicked or type; other browsers work fine; Firefox works fine after restart - same thing was happening about 1-2 years ago but want away). At any rate - I wanted to check process list as my intuition was that maybe firefox is using to much memory and maybe the os killed some process/thread and it broke the logic somewhwere. What I noticed was a a couple of "subframe" items, and what bugged me the most were one with "google.com" - I try to avoid google so I don't have any page opened with it yet it says I have 18 subframes… One possibility - extension/addon. Another - page subframe linking to google but then again - would be nice to know which page loads it…

From that thread: "User should be able to find which tab started the process"
Can these subframes actually be associated with multiple tabs, or is that impossible with Firefox's current design? If they can't, then it'd be very helpful to have them listed under their associated tabs, rather than separating them out by their separate domain name/process ID. However, since they do have separate process IDs (separately listed memory/CPU information), I can definitely see why you couldn't just have them listed in a nested way under their associated tabs, because then their memory and CPU usage would no longer be sortable by the memory and CPU columns. But there definitely still needs to be a way to see which tab started each of them.
