Thunderbird Community Forum

Good morning,

I installed the Release update about 2 weeks ago and am having several problems with it and am just about ready to switch back to the ERS channel, but I thought I'd try this first and see if it's something I'm doing wrong.

The two most consistent and major problems I'm having are:

1. I will be going along happy as a clam and suddenly all the e-mails in my inbox just suddenly disappear. So far, at least, if I go to another folder and then back to inbox, they will come back, but this is very annoying!!

2. It is constantly running at 2/3 to 3/4 the speed that ESR was running at.

Any ideas? Thanks.

All I am trying to do is change the subject line on emails. I found the add ons Header tools lite and improved and installed them. When I select a email to edit the subject line I highlight the message go to menu message>header tools lite>edit lite or edit full source neither one does anything???

Also tried opening the email go to menu message>header tools lite>change header details hit enter nothing happens. Please help and thanks in advance

Hey,

I am seeing the creation of a file "logins.db" when opening thunderbird.

When I open the file with textedit, it begins with "SQLite format 3". It looks like a script to me, including things like "ON loginsL (is_deleted, origin)" and "idx_loginsM_is_overridden_origin".

I can delete and it's recreated when launching Thunderbird.

Is this file legit? Can anyone confirm having this file, too? I'm running Mac OS 15.7.1 with Thunderbird 145.

Thanks for listening

I posted the message below almost 3 weeks ago and so far I have -0- responses. Is there anyone out there who can help?

I have several problems with Thunderbird:

- When I first open TB, my Inbox shows "No message found". I have 9654 E-mails in the Inbox. If I click on a different folder and then click on Inbox again, I can see the E-mails in the Inbox. - About once a week when I first open TB, the program begins downloading 10000 E-mails (sometimes more). All these E-mails, with the exception of a few received the previous night, have already been downloaded. This download takes as long as 45 minutes. - TB marks many E-mails as Spam even though I have previously marked these E-mail addresses as not Spam.

Any help with these problems appreciated.

Hello. I have a yahoo email address, but I receive all my emails on Thunderbird. When I set the Thunderbird account up all my settings were put in automatically by Thunderbird and everything worked fine. Since then, I have logged into my Yahoo account online and changed the password.....for security reasons. My Thunderbird account no longer works as it cannot retrieve my emails from Yahoo, and I cannot find how to change things in my Thunderbird account. Any ideas?

I am in my seventies. I have the Firebird 1 tee shirt :-) . I recently received a missive from Thunderbird asking for a donation. I click through and get a donate button. THE DONATE BUTTON DOES NOT WORK in Firefox with NoScript. WTF.

I follow some IT forums and I am to update with security and userability issues. The best advice as I see it is to TURN OFF scripts with NoScript.

After a lot of faffing about I donated. When I first started working 55 years ago I given 2 bits of advice.

 1  Never put obstacles in the way of customers paying.
 2 Never put obstacles in the way of customers ordering.

I think you should heed the first bit of advice. How many Thunderbird users were tempted to donate but were in a similar position to me and gave up?

I cannot set up my icloud email in Thunderbird.

Error implies that the password is incorrect but i know it's correct, i am able to sign in to webmail using it just to prove a point.

"Unable to log in at server. Probably wrong configuration, username or password"

I have verified server info on apple support and verified username and password is what i use on all other devices. Username and password also works on MS outlook.

Hello! I have a question regarding Thunderbird version 144.0.1.

The server is configured locally and isolated from the Internet. There is an issue: when the network cable is unplugged (no network connection), saving received emails with attachments (for example, total file size of 14 MB) to the hard drive happens quickly — about 5 seconds. However, as soon as the PC is connected to the local network, the saving process for such attachments slows down significantly — up to 60 seconds.

I would appreciate your help with analyzing this issue and possible solutions. What could be the cause of this behavior?

Thank you!

I backed up Thunderbird and reloaded it after I had been hacked in gmail, but now I have 2 profiles accessing the same gmail. One shows the gmail address and the other is my old "local" profile. The old one has my typical 16000 emails, while the new one shows 30,000 emails with no doubles. Can I delete the new one?

I have been using Thunderbird to access my comcast emails. I never had a problem with it. However, this afternoon, just out of the blue Thunderbird cannot download my emails, the following message popped up: "Login to server mail.comcast.net with username xxxxxxx failed." Then Thunderbird asks for a new password. When I enter the still correct password, it displays the same error message. I did not change anything in the settings before this error message popped up. I tried ChatGPT to get some answers, but whatever I changed it had no effect. I am attaching a screenshot of the server settings (I have of course removed my username). I would be grateful for any advice as to how to fix the issue. Thanking you.

I've been unable to use TB since July/August 2025. I don't have detailed documentation of the details, but my recollection is that an error was occurring whenever I would try to send an email. My troubleshooting led to the possibility that the problem was with the SMTP protocol.

  Please let me know whether anything more was contributed here in this forum. Meanwhile I will install TB again and try to re-created the problem.

Thanks for your help, SweetTasha

Hi,

I am trying to remove a large number of e-mails from my Inbox. The standard advice says to hold down Ctrl or Shift and select e-mails, then right click, and choose rubbish bin symbol to delete. The advice says you will get a confirmation message, but that doesn't happen. Only the e-mail right clicked on actually deletes; all the rest stay put.

I have tried deleting the trash file to force it to recreate. I have tried updating Thunderbird, but I'm already on version 145.0. I use gmail.

Does anyone know of a working method for doing multiple deletions?

I was trying to change the time emails are kept on the server so I went into "Account Settings" and now Thunderbird is locked onto this page. I get a "Mozilla Thunderbird not responding" message when I try and click on anything and I can't get out of this page nor access my Inbox. I've tried starting Thunderbird in Safe Mode which didn't work. I then uninstalled and reinstalled the latest version of Thunderbird but when it starts it goes straight back to the frozen "Account Settings" page. I've checked my profile and there is a new profile that was created with today's date. There is also a profile from June 2025. If the old profile contains all my emails and folders up to yesterday, that would be OK.

I'm just getting set up with Thunderbird. I used to use Postbox, and imported my Postbox profile into Thunderbird, which overall worked great – it got all my local email folders, and brought in my Apple email account, and so forth. The only wrinkle I've noticed so far is that it also created an account named "server7.invalid" that I can't delete. If I go to Account Settings, for "server7.invalid" it states "The following is a special account. There are no identities associated with it." The only items underneath it are "Spam Settings" and "Disk Space". There is no red Delete button for it, the way there is for my two real (IMAP) email accounts. Viewed on the Mail tab, it appears to contain only "Trash" and "Outbox", and both of those are empty. This weird invalid account doesn't seem to be doing any harm, but of course it is ugly and I just want it to go away. Help?
