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. "Sending of password for user rgh43is@gmail.com did not succeed. Mail server pop.gmail.com responded: Web login required: https://support.google.com/mail/answer/78754" 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 rgh43is@gmail.com 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
