Hello.

Can someone please help me to fix Firefox. It's terribly slow and sometimes gets stuck. I've opened the task manager and see multiple processes that don't look right - please see the attached screenshot. How can I fix this? I'm using version 124.0.1 on Windows 10.

Thank you. Johan.

You can visit about:processes in the address bar (Shift+Esc) to get more details.

Does it still happen in Troubleshoot Mode?

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)

You can check the about:memory and about:processes pages for info about all processes. There are several toolkit.aboutProcesses prefs in about:config to show more info. See also the about:unloads page for info about the tabs.
