If you happen to have another firefox running elsewhere on the same
machine
under the same username/firefoxprofile it will do that.
It will also do that if there is a firefox running on another screen
of
your desktop.
Try adding --no-remote to Firefox's startup options, or exporting MOZ_NO_REMOTE=1.
