This Morning when I tried to login as normal Firefox cam up with a crash report, so I restarted my Windows 10 think this would send the report but it came up again, and every time I tried to start, and every time I try to sign in it say can't sign in due to unknown Error, and I can't get into my emails, so I will not be able to see your replies until you have fixed the problem, Please help me ASAP.
