On Windows, start the Task Manager. (Other systems may have different names and / or commands). Select Processes. Look down the list for Firefox. Right click and select End Task. If this problem keeps coming up, ask for more help.
Tried that before posting question - did not help.
hello DragondHN
Can you please confirm if there is at all a background process running . As already suggested,can you please open up TaskManager,look under the Processes/Details tab for any instance of firefox.exe,i would suggest you to go through the whole list.
Try to delete the parent.lock file in the Firefox profile folder.
- C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
"AppData" (XP: Application Data; Mac: ~/Library; Linux: ~/.mozilla) is a hidden folder.
