I have been wondering why Firefox is opening 8 processes when i start the program. I only have the starting page tab open. I also have tried reinstalling Firefox and changing the "use recommended performance settings" in the settings, which only slowed it down. Is this normal?

Current releases have Fission enabled and in that case Firefox reserves some processes for future use (about:processes => Preallocated).

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

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)

See also the about:memory and about:processes pages for more information about all processes. There are several Boolean toolkit.aboutProcesses prefs on the about:config page to show more info on the about:processes page.
