Thunderbird Community Forum

I am setting up Thunderbird on a Win10 machine, and am having a lot of trouble adding accounts that I did not have on the two Win11 machines I have set the same accounts up on.

When adding my 2 GMail accounts, after clicking "Allow" on the OAuth popup the button would go grey the window would stay open and not close, and the account would not be added.

Changing the general.useragent.compatMode.firefox option to TRUE allowed me to progress and finally add those accounts.

I am now having the same trouble with my @hotmail.com account. When I add the account, the dark blue OAuth window pops up, but is completely empty, and there is nothing more I can do.

Things I have tried

• Reverting the above config change
• Checking that cookies and JavaScript are enabled
• Checking there is no saved password
• Used both the Account Hub and the default dialog, with the same effect.

Thanks in advance!

I have Thunderbird 142-esr on a Windows 11 computer with two users in separate Windows users account. The second user (my wife) suddenly had her gmail login stop working on TB, even though it continued working on all other devices. The symptom was that the inbox would hang trying to log on to gmail, although no error messages appeared.

My account worked normally throughout this time.

After trying less destructive fixes such as closing the application, logging off, and restarting Windows, I guessed there was an issue with her account, possibly a corrupted file. So I deleted her gmail account. When I tried to create a new account, TB accepted her credentials and the Google login came up. I successfully authenticated to Google, but installation failed when I returned to the TB new account screen. After a long wait, TB issued an error message saying the password or user name was bad.

I did two tests to isolate the problem. First, I attempted to install my wife's gmail account in my Windows TB instance. That failed in the same way. Second, I attempted to install my gmail account on her Windows instance. That worked. I concluded there was nothing wrong with her instance of TB. I thought it might be an issue with her password, although Google has never asked her to change it, and there haven't been issues logging on outside of TB. Her password did not meet Google's current requirements, so I changed it to 12 characters, mixture of upper/lower case, numerals, and special characters. That worked.

Unfortunately, during the process, I lost her settings, and it took a while to recover them from backup media.

I'm posting this more to ask if others have experienced such a problem than as a request for help, as I think the underlying issue is now resolved. Because it may be some kind of malignant interaction between TB and gmail, I thought it might be worth reporting as well.

Hey all, here's my conundrum:I have tbird on my phone, 12 different email addys all told. Imagine if you can my dismay at finding no passwords transferred using that quick transfer thing. Please tell me there is a way to fix this without having to manually re-enter every dang pass... Thanks

I stopped using Thunderbird in 2024 because of inability to change pw. I have same email accounts at comcast but would like to go back to Thunderbird. Currently using Comcast directly but loved TBird. I have a pw in use at comcast , how do I get Tbird to accept it for both email accounts on iphone and ios laptop?

I've tried everything in suggestions. Emptied saved passwords. removed and reinstalled. Server settings confirm "successfully established a secure connection....". new password isn't accepted. I DO NOT have 0Auth2 option in Authentication Method. What have I missed?

Hello there - I just changed my gmail password. I deleted the existing Thunderbird account for that gmail and created a new one. I accept the imap discovery and get the login error because it appears to be using my old gmail password. How do I get thunderbird to allow me to update the password to send for authentication? Thank you!!
