UNABLE TO USE FIREFOX BECAUSE OF REOCCURING WINDOW

more options

I've been a Firefox user for years. A few days ago I got a pop-up message box that read: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window. [Close Firefox] [Cancel]"

However, no matter how many times I click the "Close Firefox" button, the message box keeps coming back up and will not let me around it. I'd delete the program and install again, but my current Firefox has info in the Bookmarks I'd like to keep.

Any way to close the pop-up window and allow me back to the Firefox home page?

Thanks! Michael

Hi Michael, another possible reason for that message is a lock file that didn't get removed during shutdown. Check out the "Remove the profile lock file" section of the following article: "Firefox is already running but is not responding" error - How to fix.

Didn't work. Actually I got to the where a file might still be running, but there weren't any. I read and followed the instructions to delete "parent.lock", but step one... open "charms" wasn't there and a search on my computer found no such file. I also searched "parent.lock", but that turned up others having the same problem I have with no solutions. I guess it's Google Chrome for me. Seems to be working just fine. I just miss some of the features I had on Firefox.

Charms bar. We don't have that in Windows 10.

If you are looking for Windows File Explorer, hold the Windows key and tap the E key. Or for the Run dialog, hold the Windows key and tap the R key.

If you are doing a global search for files in a Firefox profile folder, make sure to turn on visibility of hidden files and folders: https://support.microsoft.com/en-us/windows/show-hidden-files-0320fe58-0117-fd59-6851-9b7f9840fdb2
