Every time I tried to access my e-mail [or send e-mail], I received this Firefox error: "Server imap.earthlink.net has disconnected. The server may have gone down or there may be a network problem." I was able to send and receive small e-mails; but I was unable to receive somewhat larger messages, including information on how to join a very important Zoom meeting. After spending 90 minutes on the phone with Earthlink, I was finally able to access some [but not all] larger e-mails by going around Firefox and going to earthlink.webmail.com directly. But, the Earthlink tech support person was unable to detect what was wrong in Firefox. I was eventually able to join the end of the Zoom meeting. After the meeting, I then went back to Firefox and was able to get and send some messages, but I'm still getting the same error message - and I'm not sure what messages I'm missing. I sure hope someone can help!
