When opening one copy of Firefox, multiple copies (4-8) open in the back ground. With multiple copies open, 8-20 open in the background.

It is quite normal to see more Firefox processes running.

  • process for the main Firefox thread (user interface)
  • one or more content processes
    you see more content processes when Fission is enabled
  • process for the compositor thread
  • process for extensions
  • process for WebRender when this feature is enabled

There are several toolkit.aboutProcesses prefs on the about:config page to show more info. You can find the current multi-process state on the Troubleshooting Information page (about:support).

  • "Help -> Troubleshooting Information"
    "Application Basics":<be>Multiprocess Windows and Fission Windows
    "Remote Processes" (Web Content)

You can check the about:memory and about:processes pages for info about all processes. See also the about:unloads page for info about the tabs.
