I've tried everything and still my Firefox says it's still running.
I've tried restarting my computer, deleting Firefox and re installing, deleting the parent lock file, and it still wont open. I would love to have my Firefox back :(

You may have checked this, but since you didn't mention it: if you open the Windows Task Manager, can you find and terminate any instances of the firefox.exe process? Ctrl+Shift+Esc opens the Task Manager, then click the Processes tab. It's worth clicking the button to view processes started by other users just in case.
