Thunderbird Community Forum

When I open Thunderbird (Mozilla), my files are not current. In other words, the most recent emails, probably since the last time I used Thunderbird, in my file folders are missing. I have tried changing the server settings but I think they are correct. Please be patient with me, I am unfamiliar with all the terminology, etc. Also, when I first enter Thunderbird, it does not recognize my password. A window opens with the message "Login to server imap.postoffice.net with username john.fn@usa.net failed." That message also appears when I click on Get Messages. Thanks for any help.

Sometimes when I receive a new email to my Local Folders - Saved search with all inboxes, it shows (1) and plays a sound, but if I don't click another folder and back, the email screen won't show the email

In a probably related effect, if I check the trash which has a lot of emails and start clicking through them, they appear as another email until I click and the title changes

What kind of a graphical issue is this and how do I fix it? It doesn't happen always, but often. It happens even when I restart in troubleshoot mode

On our Windows computer Thunderbird has always had an issue where it would pop up a message saying "Could not connect to mail server imap.comcast.net, the connection was refused". A few hours or days would go by and Thunderbird and Comcast would talk to each other again. I finally had some time to try and debug this and (of course) I couldn't get the error to reproduce but instead I kept getting an imap timeout error. I captured the error message but it doesn't tell me why it's timing out or what to do about it.

P.S. Yes, I increased the timeout value from 100 to 300 and now it simply takes longer

Details: Windows 10 Home 22H2 Thunderbird 128.3.1esr

My wife and I both use thunderbird latest release for our email. We both cannot get into the servers at spectrum email in tampabay (tampabay.rr.com) and (spectrum.net) We have used the connection information that tech support gives us at Spectrum in our Thunderbird program and it will not connect imap or smtp. They tell me port 993 for imap and 587 for smtp and to use mail.spectrum.com on both. This is a 3 week long problem and we really need help! I have even deleted my account and read countless help articles on the Mozilla support threads. When I try to use the autoconfigurator it tries the wrong smtp port 443 and mobil.spectrum.net as the servername. Please help!

My account was moved to Yahoo.com some time ago. Since then I have not been able to use Thunderbird. I get an error message "Sending of password for the user Sigma54... did not succeed. Mail server pop.mail.yahoo.com responded [SYS/TEMP] Server error. Please try again later". I have rechecked all my information several times. Seems to be accurate. I hate Yahoo and all their ads. Please help.

My Mailstore installation will not connect with Thunderbird, stating that pref.js cannot be found. Linking to Mailstore is required thus: AppData\Roaming\Thunderbird\Profiles\741kq2if.default\prefs.js

By enabling Hidden Files on my Windows 11 pc I can link to 741kq2if.default but not beyond to the pref.js 'file'. Note that my T'bird is fully installed and operational. I would appreciate advice. Ron

As the subject states: Since installing Thunderbird - 128.3.1esr (64-bit) - the app constantly crashes when running but not actively in use on Win11 Pro 23H222631.4317. Crashes do NOT appear to happen when using the app, tho it has crashed when removing duplicates from "local folders" top level, or conduction a "compress". Quite a few of my crash reports have been submitted.

Any ideas as to why?
