You can set this pref to 1 in about:config to limit the number of content processes.

  • about:config => dom.ipc.processCount.webIsolated => 1

You can open about:config via the location/address bar. On the warning page, click "Accept the Risk and Continue" to open about:config.

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":
    Multiprocess Windows and Fission Windows
    "Remote Processes" (Web Content)
