3. In the Run dialog box, type in: firefox.exe -p 4. Click OK.

Acts the same as trying to open FireFox. Also when reinstalling it said FF was open. The only way to close it was to restart the computer. However when Shut Down button is pushed, FF is not listed as a program that is open.

Hi geneo3711,
sorry you are having problems.

There are many possible reasons for problems lets look first at the ones I consider most likely:

In ordinary circumstances Firefox only runs one instance using one profile. If you have Firefox not shutting down properly that may prevent you from starting Fifrefox until you have found and killed the process. (Also look for plugincontainer which may also exist).

If you are certain Firefox is not already running then the problem is often that a Firewall or security related program is blocking Firefox. This is especially likely if you have installed new security software ,a new version of Firefox, or have tried to restore the computer.
