  2. FireFox


    That's why I suggested this for starters, for the issue you report:Firefox Will Not Open :)

    Firefox - Profile in Use

    Scroll down on that page to the "Solutions" section.
    The easiest way is to open the Windows Task Manager and to kill the Firefox process from there.
    If that does not work, then proceed to the next steps in that tutorial: remove the "profile lock" file, etc.

    Please let us know how that goes.

    Thanks,
    MM
