Multi-Process Firefox: everything you need to know https://www.ghacks.net/2016/07/22/multi-process-firefox/

Hi Robert

I think you may have miss understood my query
I am trying to understand why Taskmaster  Shows  Multple Firefox  openings - what are they doing and how can I access them to see whats going on. I have noted that with the browser open showing the home page Ie Search engine and no tabs in use, I have seen windows taskmaster show Firefox (7)  this  number varies

i am wondering if this maybe why a website I use keeps saying i am logged on on another device, also some sites seem to load clear then reload

You can check the about:memory page for info about all Firefox content processes. There can also be a process for the Compositor and WebRender.

It is quite normal to see more Firefox processes running.

• one process for the main Firefox thread (user interface)
• one or more content processes, see:
  Options/Preferences -> General -> Performance
  remove checkmark: [ ] "Use recommended performance settings"
• one process for the compositor thread
• one process for the 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
  Remote Processes

See also the Remote Processes section further down for more detail.
