I've been using Thunderbird to access my Comcast email for two years now, without problems. Except yesterday & today, when I've been unable to send or receive emails, for no apparent reason. Yet, when I connect to my Comcast/Xfinity email via the Comcast browser website, sending and receiving of email works fine. This access problem began yesterday, 10/14/2025.

Same email address I've been using for about 20 years now, and same password. I made no changes to my Thunderbird or Comcast settings. Sending a test email to myself via the Comcast email website works fine. Clicking on the "Get Messages" icon in Thunderbird results in no action whatsoever. Sending a test message to myself in Thunderbird results in about a 40 second delay (usually it's 10 seconds), and then the error message "Login to server smtp.comcast.net with username don-peters@comcast.net failed." It then asks if I want to try again, but if I agree, the same error results. But there is also the option of "Enter new password". Click on that and the same error results, without even asking for a new password. But my password is OK, as evidenced by my Thunderbird settings and being able to log into Comcast browser email.

Yes, I've spent hours on the phone with Comcast on this issue, but they were of no help. One agent claimed that the issue was with Thunderbird, not Comcast, as its webmail worked fine. Two years ago, I had a similar problem I spent hours trying to solve. It turned out the problem then was due to Microsoft Outlook on my PC regularly trying to log into Comcast to ALSO download my email - BUT using the wrong password. Comcast interpreted these multiple failed login attempts as scammer attempts, and blocked ALL email logins from my PC. I fixed the problem by shutting down Outlook. But when I just spoke to Comcast they said the current problem was NOT due to my account getting blocked by them. But they couldn't give a reason for the blockage.

So, I now believe the problem lies with BOTH Thunderbird and Comcast. First of all, Comcast is somehow blocking my Thunderbird access attempts. But Thunderbird is also at fault for not reporting a SPECIFIC email login problem, so that we can address it - and fix it. If Thunderbird can be more specific as to why login attempts are failing, I can get back to them with the evidence - and hopefully solve the problem.

I've been using Thunderbird for about 30 years now, and I hate to give it up. But if this continues, I'll be forced to abandon Thunderbird.

Hi, is there a way to get Thunderbird to move to the tray when I press the X button in the top right corner?

I've tried enabling "When Thunderbird is minimized, move it to the tray" but that just changes what the minimize button does. When I press X, Thunderbird still quits.

I've done some googling and I found this extension: https://services.addons.thunderbird.net/en-US/thunderbird/addon/minimize-on-close/

The problem with it is:

1. It doesn't seem to work with modern versions of Thunderbird
2. It lets you either minimize the window or move it to the tray, but not both (X and minimize do the same thing)

Can I get Thunderbird to close to tray only when I press X? So that the minimize button still works normally? Thanks

I think I clicked the wrong button, but now, the big, blue 'New message' button (and also the 'Load new messages' button) has disappear (please look at the attachment).

I searched in many places, as Appearance settings, "hamburger menu" >> Toolbars, Displaying (in the toolbar), etc., but I found nothing.

Does someone know how to display back these buttons?

Thanks, @eliotttak

Seid einer Woche habe ich keinen Zugang mehr zu meinen E-Mails. Es sagt mir jedes mal "Anmeldung auf dem Server imap.gmx.net mit Benutzernamen "thias.weber@gmx.de" fehlgeschlagen" Ich hatte zuvor nichts verändert und alle eingegebenen Daten sind korrekt. Auch eine Anmeldung auf einem anderen Gerät oder bei einem Freund (bei dem alles Funktioniert) führte zu keinem Ergebnis. Neuinstallation auch nicht!

For a week, I haven't been able to access my emails. It tells me every time "Login to the server imap.gmx.net with username 'thias.weber@gmx.de' failed" I hadn't changed anything beforehand and all the entered data is correct. Even logging in on another device or at a friend's place (where everything works) did not lead to any result. Reinstallation doesn't help either!

pleace help!

This is second request (can't find the first). I need to import multiple (bookoo) .EML files into TB 115.10 to later move into "folders". Several weeks ago I somehow found someway to import a single .EML file (downloaded from an old ISP) into TB -- and then got busy with other projects -- and now cannot figure how I did it. I did not use an extension (ImportExportTools NG) -- just the native tools in TB 115.10. If anyone is familiar with importing EML files -- sure would appreciate suggestions. Thanks.

I’m using the Windows 11 version of the Thunderbird app, but when I try to add my Outlook account and enter my password, it shows “Authentication failed. Please check your username and password,” and I can’t complete the Outlook setup. I’ve tried changing my Microsoft account password and entering an app password, but neither worked.

I have had Thunderbird on my HP laptop for several years. Everything has worked perfectly. BUT, I cannot receive Email, starting yesterday. When I click the Get Email icon, nothing happens. My Email server on Comcast is getting Email which I can see and read, but Thunderbird is not getting the Email. I would appreciate any advice.

Regards, Jim

I have missing buttons or shortcuts in my Thunderbird. There was a refresh button and a new message button on my tool bar, they have disappeared. Is there a way to get them back? Thank you!

Hello, I can receive email messages but unable to send them out. The error message I get follows:

The mail server responded,( bettyweber@shaw.ca sender) rejected AUP#POL. Verify your email address is correct in account settings.

What can I do to fix this in Thunderbird?

I checked with my service provider and I can receive and send messages through webmail but not Thunderbird.

Thanks. Betty

When I send an email it automatically puts a copy in my Sent folder so I can access it at a later time; but yesterday this wasn't happening. What do I do to get this to work again and can I retrieve the ones I lost? Appreciate your help. Linda
