Hi, Firefox will not open on my PC as it thinks that it's already running. First off I tried a refesh but that didn't work as the same issue occured. I have uninstalled it and re-installed again but the same issue happens. A lot of the help pages I have looked at ask you to do things via the Firefox menu but as I can't even open a browser I'm unable to make cahnges.
