Computer must be restarted for updating to continue firefox
If you’re still experiencing this problem, consult the Profile in use wiki page on mozilla Zine for more technical solutions to rare problems.
Once you’ve located firefox.exe, select it and click the End Process button.
Firefox won’t appear in the list of running applications because this list only shows applications with open windows. (On Windows 8, you should find Firefox under Background processes.
You can also click the Details tab to see a full list of processes.) Type the letter f and you should instantly jump to the process.
