I had Firefox crash a few times, lost some windows, but FF saved two windows it seems. So, I started using FF, but have noticed a few odd problems that I cannot control. For example, some new tabs seem to never open after I click on 'Open in new tab'.

Another example, I can delete tabs, but when I close FF, and reopen FF, the tabs 'come back'!

One thing I've noticed is that Windows TASK MANAGER shows several FF windows, but I really only have 2 active FF windows (see image attached).

I've tried to perform and END TASK on some of the FF processes in TASK MANAGER, and then end FF, but the processes I ENDED, come back anyways on FF restart.

Forgot to mention - I can open CHROME browser, and then open a FF forum page - but when I copy/paste the URL from CHROME, into FF browser, and then do a PASTE & GO - that page will not open in FF. It just shows an empty page with the little circling thingy.

Hi

It is quite normal to see at least four or five Firefox processes running because there are several processor threads used for various components.

  • 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

More processes may be present for other features like extensions.

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.

Thanks for that feedback. I did not realize. I thought the 'extra' processes were failed attempt for FF at opening my lost windows. I suppose I may have messed up something by ENDING those TASKS?

Do you have any idea why the tabs I delete just come back after I restart FF?

Or why I get that page with the 'spinning arrow' when I tried to login to FF from my FF browser, while I can login from my Chrome browser?
