''<p>brashnz [[#answer-1693210|said]]</p>'' <blockquote>I'm having much the same problems, but I only have ONE pop-up......Today as I write, it is December 10, 2024. This only started at the beginning of December. I have emails for November 30 but cannot get any since on my computer. </blockquote> The user who reported the problem was asked to post images and it was discovered the problem had nothing to do with email account. The pop ups asking for password were due to a gmail calendar and gmail address book. It would be helpful if you posted an image of the pop up you are seeing. But it does not sound like the same issue as reported by user. In your case it sounds like it is specifically effecting the email. Gmail/Google need you to say Thunderbird is allowed access to the server otherwise google/gmail will block access and you will not be able to see emails in Thunderbird. It would also be useful to know what server settings you are currently using and type of mail account. In Thunderbird Help > Troubleshooting Information Scroll down to 'Mail and News Accounts' section Post an image showing all the info in that section. However, before you do that you may find if you do as Google request - enter password to prove you really are you and then click on the 'Allow' Thunderbird access option, everything will start to work as expected.
