Thunderbird Gmail OAuth2 failing with Thunderbird detected a potential security threat and did not continue to accounts.google.com

TB version: 115.1.0 (64-bit) Windows 10 (corporate laptop)

Fresh laptop, fresh install of TB.

When trying to connect email@example.com (not really my email), TB correctly detects that my domain is hosted at Google, configures IMAP and SMTP for OAuth2, and pops up the window to authenticate.

Instead of an authentication prompt, I'm met with this error:

URL: https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=<CHOMP>aq8lmia8j<CHOMP>.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%40example.com

Text: Did Not Connect: Potential Security Issue

Thunderbird detected a potential security threat and did not continue to accounts.google.com because this website requires a secure connection.

After the automatic upgrade to 115.2.2, I have lost access to all my folders, emails and calendar entries. But I can still see my addresses by using Tools/Address Book, and my filters by using Tools/Message Filters.

When I started Thunderbird for the first time on 115.2.2 I got to the usual message page which had all the tabs of the "open" emails I had when I last closed Thunderbird. But there was no sign of my folders and I couldn't get to any other messages (See first screenshot). I also had a second occurrence of Thunderbird running (I could have hit the icon a second time) that didn't show the tabs I had on the first screen. (No screen shot)

On a previous post here https://support.mozilla.org/en-US/questions/1424153 it was suggested that I try Troubleshoot mode. That made no difference and at that time I had no folders showing, and just two tabs. I suspect after that I deleted the tabs.

Now I get a completely blank page in what is usually the message/folder area. Also the button for the address book above the message pane has now gone disappeared (Second screen shot), and I can find no way of accessing my previous (10years+ of messages).

It looks to me as if something is wrong in the profile.

Where do I go from here?

Every morning when I open Thunderbird I receive the notice that "Thunderbird can't update to the latest version." but I am already running the latest version (91.9.0 as of this writing, screen capture attached).

None of the following have worked to resolve this issue yet:

  • Download and install from "Download Thunderbird" link in notice.
  • Uninstall and re-install from fresh download.

Any thoughts what I'm doing wrong, or what else I can try?

Thank you.

Thunderbird is completely unusable in the latest release. Attempting to set up a gmail based account results in

"Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to 192.168.1.250. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

That's it. No options, no explanation, no KB articles, nothing. It just doesn't work. But why is Thunderbird trying to open a web connection to my local machine? If it's trying to talk to itself, why can't it? This is clearly an issue with trying to authenticate to Google as it happens after auth, but come on, this is a given requirement these days. If your app doesn't work out of the box (MacOS 13 btw), it may as well not exist for the OS, so this is very confusing.

Trying out older versions was a real comedy of failures as well. Too old and it's just a disaster. Too new and it just self updated to 115 again which doesn't work. So kinda seems like this is not a functional app anymore, at least not on Mac. Baffling. I guess it can only be used with legacy style email systems.

I understand that Supernova changed the database format of email storage making rollback more difficult.

Well, either I get to roll back to the old UI, or the pre-Supernova Tbird, or I'm done with Tbird and done donating. This update is absolute shite and not being warned of the changes it would make was really, really shitty.

So how do I roll back, oh geniuses who developed this new shite Tbird?

1. I am customer of Ionos, formerly 1&1, who host my email address.

2. Ionos have advised me I will be unable to download emails from their server after 25 April unless the email program supports TLS1.2 or higher and they said Thunderbird version 52.00 supported TLS1.2 or higher.

3. I have 2 PCs with Windows XP SP3 and 1 laptop with Windows Vista. Ionos say the only email program I will be able to use after 25 April using the latter 3 devices to download emails from their server is Thunderbird version 52.00.

4. Is there now any means by which one may install Thunderbird version 52.00 onto a PC with Windows XP SP3 or, alternatively, a laptop with Windows Vista?

I'm sorry if this topic has already been answered.....and I know it has.....but I have been reading and trying things for almost 3 hours.....I need help!!! I have at work the Thunderbird eMail that goes through a different server. I followed the directions and copied the "Moving Thunderbird Data to a New Computer" to a flash drive. I used that and have all the files that were on it, now on my at home computer. It appears that everything is good up to that point. I even get the window that shows that Thunderbird recognized my other server's setup, however when I choose "OK" it gives me an error message that it is already on the server. I can see the Thunderbird email system on my home computer. But I can't get it to show any of the emails that I know are there from my work computer and I can't get it to download. I'm not sure if I have been clear enough, but I hope either someone can help me with what I have provided--or provide me with directions on how to do the install--EASY directions--because I'm unable to follow what I have found so far. And a reminder--I do still have all the files that I copied to the flash drive--so I could start all over again, and it would not be a problem. THANKS SO MUCH IN ADVANCE!!!

I just want everyone to know, I will NEVER again update Thunderbird. I do not like the constantly changing layouts. I do not like layouts changing without my consent or knowledge. You are NOT user friendly any more. While some may like your approach, I do not. Frankly it seems that most software is becoming less and less user friendly and more like, do it Thunderbird's way or else. I hope someday, someone will put out a simple email client similar to your older issues. Also, I do not like the continual nagging to update.

Thunderbird was working under MacOS Ventura, and I do remember setting up 2 Step Verification to make that happen. Several other websites were later added, apparently using 2 Factor Authentication, instead. I followed the instructions to upgrade MacOS Ventura to MacOS Sonoma. Everything except Thunderbird continued to work correctly. I tried to use the "old" app specific password to get Thunderbird to work again, but that failed. Then I tried to find the MacOS tool under Sonoma to allow me to regenerate the app-specific password for Thunderbird, but it's no longer available (replaced by 2fa, I assume).

1. How do I restore 2sv support for Thunderbird under Sonoma? 2. Will it cause the newly installed 2fa apps to fail?

I have "lots" of stuff in my Thunderbird email repository that are no longer accessible via what remains of Thunderbird (basically, the directory structure). Please help me recover from this disaster.

Thanks!

TBird 102.2.1 - just updated . . . and discovered that doing so caused several folder modifications I had just completed in the previous version disappeared. Really, really helpful . . . not.

Was in the midst of copying email files/messages to an external drive; 3/4 of the way through, in checking the "finished product" over there on the external, I discovered that -- regardless of what date the email had originally, TBird was changing all of the message dates to today's! That's really, really useful . . . I guess . . . in someone else's reality. My reality is that when I'm backing up email messages I have a reasonable expectation that they will each accurately reflect everything associated with the original(s).

So: How does one tell TBird to leave the original date(s) alone and copy the message(s) intact?

Guess it's now looking as if I will have to start this process all over -- and attempt to not seriously begrudge a program that makes such an unwarranted and unexpected change . . .

Thanks for any helpful information; appreciated.
