Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.
I attempt to open firefox and despite firefox NOT being open I get the following message "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."
Once restarted it works fine but does re-occure

Press CTRL+ALT+DEL, open the task manager and click on "Processes". If Firefox is still running you can close it from there. Not a complete fix but it spares you the reboot.

- search for network.seer.enabled
- Set that to false by right clicking and selecting Toggle
