Explain Parameters of firefox.exe
Hello,
On a Windows 10 Task Manager panel I see the Firefox application running with parameters like:
"C:\Program Files\Mozilla Firefox\firefox.exe" -contentproc --channel="9328.0.2143754315\1267831822" -parentBuildID 20210622155641 -prefsHandle 1708 -prefMapHandle 1700 -prefsLen 1 -prefMapSize 261986 -appdir "C:\Program Files\Mozilla Firefox\browser" - 9328 "\\.\pipe\gecko-crash-server-pipe.9328" 1652 gpu
1) What do the parameters "-contentproc --channel" and value "\\.\pipe\gecko-crash-server-pipe.9328" mean?
2) Where could I find a list of the parameters I can use with firefox.exe?
I've attached a screenshot of task manager Command line column that shows each of the Firefox running processes
Thanks

These are content/gpu process identifiers. You can't use it with a main firefox process.
Thank you TyDraniu. Why do you think the command lines are showing this way ? By the way, I made no changes to the installation of Firefox.
That are separate sub processes used by Firefox and Firefox communicates with these processes via UDP ports and are launched by Firefox with their own parameters.
See the about:memory page for info about content processes.
It is quite normal to see more Firefox processes running.
- process for the main Firefox thread (user interface)
- one or more content processes, see:
Options/Preferences -> General -> Performance
remove checkmark: [ ] "Use recommended performance settings" - process for the compositor thread
- process for extensions
- process for WebRender when this feature is enabled
You can find the current multi-process state on the Troubleshooting Information page (about:support).

See also the about:memory page for information about the process IDs.
