Frequently getting message Firefox is already running

March 8, 2012 at 12:37:46
Specs: Windows 7 Professional 64-but, 6GB
I frequently get a message firefox is already running ... please close firefox or restart
Ive Googled for help on this and have tried the suggestions of 1)check for Firefox process in Task Manager, and 2) check in C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\5tb21go4.default and delete the file named Parent.Lock But neither the process in Task Manager nor the parent.lock file are there and my only option is to cold boot my computer.
I have even reinstalled FF to no avail, the issue is intermittent.
Is there anything else I can do to resolve this issue as it is now becoming a pain. I am seriously considering binning FF altogether and going back to IE.
My system is HP Pavilion G6 running Windows 7 Home Premium 64-bit with anytime upgrade to Windows 7 Professional 64-bit. I have a 670 GB HDD 6GB Ram, Intel Core i5 250M 2.5GHz CPU

It is running so that is why you get that message. As to why it is running is another issue. May be any number of reasons from simple to complex to security issues.

There is some edit that allows multiple instances that may be the most easy fix.

If you want to fix it correctly then do a clean install of the OS and then apply all updates and security software and then install only the latest FF.

Hi jefro.
Thanks for your help but couldnt find multiple instances listed in about:config.
I bit the bullet and completely removed Firefox again, this time completely deleting the Mozilla Firefox folder in Program Files (x86), and thus the profile folder. Dont think I did this the last time. Noob error on my part.
