This is a usual error caused by some addons.
Please disable all addons and try it again.

I get this message, also in safe mode: 
"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."

To reproduce, close Firefox and restart it fairly quickly.
