Hi - this message appeared on the desktop this morning when I tried to open Firefox. There are lots of solutions when I google it, but they are very confusing and seem to give a variety of replies about which files/folders to uninstall, remove or rename.
Can anyone point me in the direction of an idiot's guide on what to do? I didn't have sync turned on (but I do now on the laptop) so I assume if I log in on the desktop with my account details, my bookmarks etc will reappear. Hopefully.
Thanks, chaps, I'll give it a go if it's as easy as that. I thought I remembered seeing something somewhere that, if you didn't remove some file or other, a message about a profile being in use appeared.
