windows 8.1 doesnt close firefox properly
I have a niggling problem with Firefox -
I am running the latest version of Firefox ( 35.0.1 ) and the latest version of Windows 8.1 - there are no updates available from Windows Update.
Regularly when I close Firefox by clicking the X in the top right corner, the Program seems to close, but wh en Igo to open it again by clicking on the Icon that I have pinned to my Taskbar I get a window with the error message :
"Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."
I then close that Window and Fierfox restarts.
Thanks.

Hello coconut11, can you replicate the issue when you click the 3-bar menu and then click exit ?
thank you
Since everything is in firefox profile which needs to be unlocked at time of opening of firefox. Do following steps which helps to you to solve this problem:
- Open Task Manager by right click on empty side of taskbar(located in bottom generally of windows) or press CTRL+SHIFT+ESC .
- Now click on Process tab and search for firefox.exe .
- Right click on that and choose End Process with Yes when asked by Task manager.
- delete all firefox.exe file from process if any other are existed there.
- now run firefox normally.
Again, if the above not works then try to Remove profile lock :
- Restart windows and not start your firefox after that.
- Go to Firefox Profile folder https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data#w_finding-your-profile-without-opening-firefox
- Delete the parent.lock file.
now run firefox.
Do you have the Firefox icon on your quick launch? Right click on it, and select Open New Window. Sometimes this works. If it opens, close it by Menu > File > Exit.
This is not a cure but will make it easier if Firefox locks up in Windows. https://support.mozilla.org/questions/997866 {web link}
Start Firefox in Safe Mode {web link} While you are in safe mode;
Type about:preferences#advanced<Enter> in the address bar.
Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.
Poke around safe web sites. Are there any problems?
