After escaping from the blank screen it says it could not access server. But my credentials are copied from my gmail login that works fine. And I have checked the configuration with other gmail accounts that are running in Thunderbird and they are the same. So why am I getting a blank screen? How do I get my google permissions authorization form to show up? This procedure now fails to work for a gmail account that I have put into Thunderbird successfully in the past. I went to a lot of trouble to get all my email accounts into Thunderbird. I really don't want it to fail me now. Thank you to anyone who can help.
