Hi there,

I'm a first-time user of Thunderbird and I really like its functionality and interface, however, I can't succeed at adding my Google accounts - every time I get a message one of the following messages: "Warning: Potential Security Risk Ahead" or "Did Not Connect: Potential Security Issue. Thunderbird detected a potential security threat and did not continue to accounts.google.com because this web site requires a secure connection."

I tried changing the configs but nothing works. Could you please assist on this?

Thank you for your cooperation! Best regards, Mirela

For one thing, your id needs to be the full email id. Leave password off.

I ran in to this issue today.

Clean install of Thunderbird, trying to connect an account I have hosted there (@mydomain.com). TB detects that it is GMail hosted, configures IMAP, then tries to pop the window for login/authorization from Google, but instead throws the error mentioned above.

I tried TB in Troubleshooting mode. I tried setting the following config after reading an article that was similar, but not the same. This did NOT solve the issue:

general.useragent.compatMode.firefox true

TB version 115.1.0 (64-bit)

Edited to add the following (with sensitive bits redacted) The pop-up URL is: https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=<CHOMP>-aq<CHOMP>3t1hgqj.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost&scope=https%3A%2F%2Fmail.google.com%2F+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcarddav+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fcalendar&login_hint=<USER>%40<DOMAIN>

I wouldn't mess with the user agent, that isn't your problem.

What is your anti-virus/security software?
