I use Firefox as my primary server for my Gmail account. Today, when attempting to access my email, I received error messages that the email message could not be opened, and to try again. When I tried again, I got a message that Firefox was working offline, so I needed to uncheck the offline box. The offline box was indeed checked (but I did not check it), so I unchecked it, and the same message occurred. I still cannot get into my gmail through Firefox.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.
