    Firefox already running error in Windows 8

    I have installed the Windows 8 OS in my PC and also installed the Firefox browser which I use frequently. It was working fine for sometime but now I am not able to open up the Firefox browser at all as it just gives the error message as “Firefox already running”. How to resolve this problem now? Can someone please help?

    Try a couple of ways one after another if they works.

    Invoke Task Manager,

    Check which of the Firefox process are running,

    Select them, click END TASK to close the process.

    Exit and run Firefox. Is it running ?
    If yes try some more time exit and rerun Firefox, but if the Firefox still says Running in the background,

    Uninstall Firefox, Control panel--programs--firefox--uninstall,

    Download another firefox version, install afresh, done.

    Hello my dear friend ...


    Kindly follow the below process


    First of all wait for a few minutes

    And then End firefox.exe in the Task manager

    Firefox won't appear in the list of applications

    Restart your computer

    Remove the profile lock


    So if you really follow these process the problem will really get solved


    VERY GOOD LUCK
