1385736 - How to distinguish between content processes and Extension OOP processes?

Status: RESOLVED FIXED

(Core :: IPC, enhancement, P2)

Description

[YF (Yang)]

I can see "gpu" for GPU process - command line from Process Explorer and about:memory, but how to confirm which process is the Extension OOP process?

Because I see 5 + 1 (main process) processes have 100+MB memory usage, as dom.ipc.processCount is 4. I want to investigate how much memory is used from extensions, and check the pid from about:memory.


Therefore, I suggest the process list - command line, about:memory and about:performance annotate the nature of the processes.

Note: I guess this should be done with multiple bugs, so this bug is a question for confirmation.

Once bug 1383978 lands, you'll be able to look in about:memory.

Thanks.

As far as I can see this is fixed. about:memory displays the pid of the WebExtensions process as mentioned in comment 2 and the process is now also titled "WebExtensions" in the system process explorer.
