When I check for programs running in Task Manager, there are 4 or more instances of Firefox running. Why.? This never used to be the case, but ever since Firefox forced me to update to it's latest browser, I see more than one instance. Is this a bug in Firefox, or some other type of hack going on.

It is quite normal to see three or more Firefox processes running.

  • one process for the main Firefox thread (user interface)
  • one or more content processes set via
    Options/Preferences -> General -> Performance
    remove checkmark: [ ] "Use recommended performance settings"
  • one process for the compositor thread (Windows;graphics)

You can find the current multi-process state on the Troubleshooting Information (about:support) page.
