Login Error when logging to Gmail. "Sending of password for user email@example.com did not succeed. Mail server pop.gmail.com responded: Web login required"
I just got a message from Google that someone tried to access my account. They suggested I change my password, I did and now I cannot access my emails using the program I usually use to access my gmail accounts, Mozilla's "Thunderbird". I can get my mail but I have to log into Google's program to get them. I have 4 and they all forward to the one below. When I open TB I can only see the emails that arrived before I changed the password. No new ones, I tried to send a test from my wife's gmail account & it sent. Didn’t show up in my in box on TB. I see it in Google's email program in box but It doesn’t go to my in box in TB. I also can't send any messages from TB. TB request that I log in but I just keep getting this message when I try to log in. I'm using the same password I have to use to get into the gmail program so it is the correct password as I can see all my email in my in box.
Here is the message I get every time I open TB or try to send any message.
When I try to send an e mail in TB then this box pops up: ____________________________________________________________________ Google
Sign In to continue to Mozilla Thunderbird e mail
E mail or phone firstname.lastname@example.org
More options NEXT ____________________________________________________________
Clicking on anything in this box does nothing, I cant get it to go to Next or anywhere.
I have used Thunderbird for years and my wife's account still works with TB and still has the same old password that I had until I changed it.
Unless I changed or checked something I shouldn’t have when I changed the password & updated the contact info. I'm at a loss. Any Ideas what the problem is. Thanks

Did you delete the old password before entering the new one?
No, Actually I did not know i should do that. I didn't delete it until later when I read about it in Mozilla. When I went into Saved Passwords I had 2, the old password back from Oct 2016 & the new one I had just told TB to save when I input it when asked this AM. Hopefully this didn't screw up something but I was all ready having the problem the 1st time I opened TB after I changed my password in G maiil. I have changed the passwords in G mail before with no issue as far as I can remember.
Did you enable 2-step verification on the account or enable/disable access by 'less-secure apps' on the Gmail website? Does the account use OAuth2 authentication instead of 'normal password'? There are several pitfalls to getting a gmail account set up in TB, apart from the issues brought on by changing passwords.
"Next" is broken. See https://bugzilla.mozilla.org/show_bug.cgi?id=1359297
Fixed in 52.1.0
The issue still exists in 52.1.0 (32-bit) on Windows 10 - at least for me... Same exact behavior as OP described.
I was able to work around the OAuth issue by changing settings for gmail account to no longer use "OAuth2", but "Normal Password". Setting in TB 52.1 (Windows 10) can be accessed via 'hamburger icon', Options, Account Settings. Under 'Server Settings', set the "Authentication method" setting to "Normal password".
Notice - Normal password is LESS secure than OAuth which is LESS secure than 2 factor. Assuming you only configure TB on a well known computer, it should be ok, however, it is the LEAST secure authentication method.

ITDawg, Are you on a Mac?
No, Windows 10. My Windows 8.1 system is already configured for "Normal Password".
