Keep on downloading Mozilla Thunderbird Release but it keep coming up as ESR. How can just have Release? My email account with Mozilla is [edited email from community support forum] @pc-q.net can you reply there.

Thunderbird has stopped receiving messages from @embarqmail (Sept/25) and @gmail (Mar/26) stating the password is incorrect. The passwords are correct as I can still access these accounts online. I have repeatedly updated the passwords through the popup message, but my emails are still not delivered or sent. Lucille

I just wonder why all mails suddenly seem to be totally disappeared. Without any warning. Althoug there should be 20 mails (which figure has only been creasing for the time being/already for hours. :( Also all ready models/musters seem to be deleted. So I can't add my usual signature as easy as usuaylly:

Heli Mäki [edited] FINLAND tel. [edited] < [edited] @gmail.com>

I can't find my password. I have the encrypted password. Could you please provide me with the unencrypted one. I am locked out of a good solution for want of this item. The encrypted password is in the login information: {"nextId":8,"logins":[{"id":7,"hostname":"mailbox://pop.orange.fr","httpRealm":"mailbox://pop.orange.fr","formSubmitURL":null,"usernameField":"","passwordField":"","encryptedUsername":"MEIEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwcECKOq5c7et8tSBBg8bhRC2mUKTBdmSXk1HOIw+kJxVt2gG/Q=","encryptedPassword":"MEIEEPgAAAAAAAAAAAAAAAAAAAEwFAYIKoZIhvcNAwcECOabVSCGHBLGBBiqEqUXu8w7N4eAi09k0ZOIVAcs0chiziM=","guid":"{a798443b-98d1-47aa-bfe6-130fccad60d8}","encType":1,"timeCreated":1747819721033,"timeLastUsed":1747819721033,"timePasswordChanged":1747896607191,"timesUsed":1,"syncCounter":3,"everSynced":false,"encryptedUnknownFields":null}],"potentiallyVulnerablePasswords":[],"dismissedBreachAlertsByLoginGUID":{},"version":3}

I would appreciate your help. My account has been locked out of a good solution for lack of a critical piece of information.

Importing CSV address books does not work properly. The resulting folder cannot be accessed by emails to be sent.

The imported Address Lists cannot be used in an email as a list. The error message is that the address is not a valid email address. However, if a new Address List is created with the contents of the imported file manually copied, then it can be used as an email address.

I also found that clicking on an individual address in the imported csv, will open the individual email address.

So the addresses are valid but the list is corrupted.

Trying to start using new laptop HP Omnibook 7 14". All going well, but small differences are a problem. I think I had it all yesterday, but today when I read emails and put them in "trash" I could not find the empty trash icon, not in the trash icon nor in the menu above.

When I search for a name in Thunderbird mail e.g Lennart, nothing from 2026 comes up, only older mails from 2025-12-31 and backwards. if I search on his e-mailadress, e.g l.name@ppost.se it finds avery mail. What is wrong?

My inbox folders used to show a yellow diamond when there was new email in the folder. The folder colour does still change to blue to indicate unread email. When I open a folder, the yellow diamond still shows up on new email, as well as the unread flag. What have I done? How do I configure Thunderbird to show that yellow diamond on folders with new email?

What does the icon that shows (for a while) against the SUBJECT line of messages indicate?

After some time, or perhaps following my general activity within the application or some other trigger, it seems to disappear for reasons I have yet to understand.

I attach a screen clip showing four of these icons ("2025 - STILL TO REVIEW" is one of my user-created folder names.)

Secondly, is the answer to the above question available already in online help for Thunderbird? If so, and since I haven't found it yet, I would be grateful to be pointed towards the relevant article. As a new user, I expect it would tell me other things that will be useful for me to learn!

I am using version 146.0.1 (64-bit).

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

I cannot send from an Office365 account but can get mail - it simply says 'sending' but nothing happens.

I am using Owl (paid subscription) for my Office365 account.

I also have another email that is a simple IMAP account and that works beautifully!

I have a few folders I need deleting.

They do not appear in my webmail (mailserver) but do in Thunderbird - I have tried so many methods on your forums, but nothing is working - can you help?

For some time now my primary email address gets wiped clean every night and is empty every morning. I have to transfer received mail to another input address to keep it safe!

I have Version 140.8.0esr | Released February 24, 2026, for Linux Mint (up to date)

I have a CardDAV address book on a Nextcloud instance that i want to sync to Thunderbird.

When i open Address Book and the clikc on " Create a new address book" the Account Hub modal window opens. None of the 4 options (including Add Remote Address Book" do anything, i.e. I can click as much as I like but nothing happens.

I send out golf group e-mails. I have myself (e-mail address) in the group, so it will also come back to me. The server keeps rejecting my group e-mails because it says my e-mail address is incorrect, I have checked it several times and it is correct. I even edited it to be sure. Why is the server still rejecting it?

Thanks for your time....Paul Smart psmart@triad.rr.com
