I try to lauch firefox but I get an error message saying that the programme is already running. I need to close the program and re-start. However the programme is not actually running.

I can however launch firefox as an administrator but thsi is theonly way. I have unistalled it then re installed it but with no success. I still get the error message. I have now uninstalled it again.
