Firefox tells me to close program because Firefox is already running

Firefox tells me to close program because Firefox is already running. When I close Firefox then re-open Firefox: same message. When I check Firefox in Task Manager, there are anywhere from 6 instances of FF running and sometimes up to 24. Something needs fixed.

"Firefox is already running, but is not responding"

External links from other applications will be rejected with this message if firefox.exe was started with the -no-remote command line parameter.

It also appears if you quit Firefox and try to re-open it too quickly before it has had time to completely shutdown in the background.
