Which operating system you are using?
windows 8, its the updated version.
In windows you need to forcefully close it through task manager.
1. Open task manager by right clicking task bar and select start task manager.
2. Go to Processes tab. 3. Scroll to find the process name : firefox.exe
Select it and Click the "End Process button below."
Then run the firefox again from shortcut or whatever you want to do.
I do not have a process tab.
Then you should click on "More Details" and you will be right back in Process tab.
