Upon starting up Firefox (which is normally the only browser I'll use) I'm getting this error: Profile Missing Your firefox profile cannot be loaded. It may be missing or inaccessible. I have tried doing a clean reinstall. I've try restarting - computer and program. Tried restarting program in safe mode, even after a clean reinstall and I still get the same error. HELP! I am running Yosemite 10.10.2
