FireFox Will Not Open Protective Browser

When trying to open my protected browser with firefox I keep getting "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." I have refreshed and re-installed Twice! I have followed the instructions to go to file (using %APPDATA%\Mozilla\Firefox\Profiles\) and make sure it is NOT Read-Only and to delete the parent.lock in it. Yet it keeps going to Read-Only and the parent.lock keeps re-appearing. The day before everything was working. I have tried Protective Browser with other browsers and it works. 1. Why is the Protective Browser not working? 2. Why is the File going to Read-Only and 3. Why is the parent.lock keep returning? Thanks

Is "Protective Browser" some kind of third-party software?
