Greetings- I was using my browser (single window, three open tabs) and I checked task manager - Firefox has several concurrent processes running and I don't understand. I understand the sandbox and one process having several child processes, but this I believe is suspect.

I also noticed that in the "Security at a glance" window in Win11, my icons have changed - there's a weird white box on most of the security icons. I'm thinking I may be under some sort of virus/trojan, etc., yet I've ran antivirus even in prior to boot and got nothing

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)

See also the about:memory and about:processes pages for more information about all processes.
