On January 13, 2025, Thunderbird was changed in a way that made it not function with Optus.

Please give me very precise instructions on how to make it work again.

I have donated to Thunderbird's development, but have not used it for 10 months because of this problem.

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 was having massive issues with TB when it auto updated from 142 to 143. Then last week, just when I thought I had everything restored, the damn program auto updated to 144.

I still can not "delete" messages or send anything.

I downgraded to 140.3.1 at least with that version I could delete messages. But I still could not send anything. TB send would time out and a window would pop up asking me to "sign in with my ISP".

And like others that have posted, I too lost folders on the new updates.

This whole series, 14x is a bust IMO.

Confused. Version 144.0.1 | Released October 16, 2025 Says 32 bit. I thought I downloaded 64 bit.

Problem: Freezes when I click anywhere on TBird desktop

How do I address the freezing problem?

Thanks Robert

13 Nov. I have been dealing with the problem of the requirement to sign in to Thunderbird using Google. It does not work. I enter my e-mail address, click next, and get a second window that says "Error 400". I tried to get some help with this through a company listed on the internet as Just Answer. That turned out to be a scam.

Someone called me this morning, offering to help me with this problem. The person was from the company The Web Services. While the technician from Web Services was working on my computer for a while to restore my Thunderbird files, he told he that they kept losing the internet connection to my computer. He said they had determined that they kept losing the internet connection, because some hackers were hacking into my computer, while they were working. He showed me a lot of evidence of hacking on my computer, indicating that the 2 technicians from Just Answer who had helped me the day before through long chats were hacking into my computer the entire time they were chatting with me, going through steps they said would solve the problem with having to sign in to Thunderbird using Google. I think the people from Just Answer had tried to create a Thunderbird back-up profile, but had not done it correctly. As a result, all the data within Thunderbird was lost. I cancelled my subscription with Just Answer today.

The technician from The Web Services was able to restore my Thunderbird, including the many local files I have. Some additional formatting of the site still needs to be done, and the correct server settings need to be set up. That is to be finished tomorrow morning. The Web Services person also sold me an anti-hacking firewall, which is supposed to also provide network security.

I am concerned, because on the Mozilla support page, it specifically states that Thunderbird does not offer phone support. I gave this company access to my computer today, so they could restore my Thunderbird files. The Thunderbird files have been restored. Now I see that the issue with trying unsuccessfully to sign in to Thunderbird using Google is still there. So I am right back where I started over a week ago, trying to find someone who can solve the issues that come up when I try to sign into Thunderbird with Google.

I am somewhat suspicious of the company The Web Services, because they called me and offered to fix the problems I am having with signing in to Thunderbird. Please let me know whether it was unwise to let them work on my computer today. Could this be another scam? Thank you.

Somehow I have many emails on the same topic (like 40 or 50 of them, going back over several months, even years) all piled up on top of each other, and then I have to close them all one at a time when I need to switch off my PC.

It does not seem to be due to being in Conversation View. I have followed 2 or 3 videos re how to get out of Conversation View, going into settings etc, only to discover I appear to be not in it in the first place.

Is threading different from conversation view?

I have been using Thunderbird for many years, but 3 days ago my Thunderbird icon disappeared from my desk-top and I could not find Thunderbird among my programs. This included my email storage folders. This also happen on my wife's computer at the same time. I searched for my emails and found them through google. It was just a list with no organization or folders. I took my computer to a well established computer shop for them to investigate. The next day my wife's computer was just fine, icon was back on her desktop, emails in order and her storage files were back. I am trying to reinstall Thunderbird, but I'm getting nowhere. Please help! Sending me an email won't work.

Sorry for the long=winded message but I figured it would save time to explain the steps from the beginning.

I've been using Thunderbird as an OSB for my archived messages from Apple Mail. In that scenario I create a .mbox file of all messages I want to save from a particular year and then import that into Thunderbird into a local folder with the year as the folder name. The version of Thunderbird where I was doing that is 115.10.1

I started testing Thunderbird version 139.0.2 as an Apple Mail replacement with only 2 of my email accounts.

Now I want to convert entirely out of Apple Mail. First I made a backup copy of the entire Thunderbird folder located in the User/Library folder onto an external hard drive that I then disconnected from my computer.

Then I downloaded the latest version 145.0 (aarch64) and installed it. (I still have the other 2 versions on my system) I opened it up and got into the profile manager (troubleshooting then about profiles) and discovered that I have 4 of them. I made the one that contains my archive the primary one. It does not have any connections to a live email account. I've only ever imported an .mbox file. Everything that I've archived is there. This is profile Number 1. I renamed it Archive so I could keep track of it.

Then I opened up each of the other 3 profiles in a new browser in sequence to see what they were.

It appears as if I have one that is empty. it opens up wanting me to set up an existing email address. I closed that one down. It's called Profile number 2.

The next one appears to be the current one for the 2 test email accounts. It has them properly configured, showing messages in the inbox and with the messages that are supposed to be archived off in the local folders I had created as I expect. I am calling this one profile number 3.

The third one first had me add the passwords for the 2 test accounts and then it is pretty close to number number 3 but is missing some of the local folders. This is called profile number 4.

Want I want to end up with is 1 profile. I would prefer to start with the one that has all my archive messages in their local folders, and then add the test accounts including all their messages from profile number 3 with its local folders. Once they are safely moved and part of the Archive profile I would like to delete all three numbered profiles. Once I am down to only one active profile and no others lurking about I plan to slowly start adding the rest of my email accounts moving them one by one out of Apple Mail and into Thunderbird.

I've read the various articles on moving out of Apple Mail into Thunderbird So I believe I can add the Apple email accounts to my Archive profile successfully. I have the import tools so I can import the .mbox files from Apple mail into those accounts.

Where I'm stuck is I can't seem to find an article that gives me detailed instructions on how to combine profiles within Thunderbird. All the articles imply keeping multiple profiles active and I would prefer not to do that.

I am sure I am just not searching properly but I am at a loss as to how to proceed. I do not want to delete any profiles or start adding more accounts until the profiles are cleaned up.

Thanks for reading this long explanation and I appreciate any help anyone can provide.

I quite often get this message, though it tends not to be a problem later "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox"

One of the solutions seems to be Compact a File. How do I do this?

Hello, In Tbird 145, my calendar does not show the column header for the weekday 'Friday'. All six other headers are displaying correctly. This is also occurring when 'Workweek days only' is selected. Thank you.

Hello,

When I try to save attachments from emails directly on my Computer, they never arrive at the destination folder - not individual files nor "save all attachements". Although the procedure '(left button menu - save - [navigation through file system till to the destination-folder] - save here') is "normal" and does not give any error message.

I can only save attachements, when i first open them (e.g. in word), and save them from there in its destination folder. This is quite a complicated procedure .. one should be able to save attachments directly from Thunderbird, without opening it.

What is the reason for this problem? Are there any options, is it a local problem (but it is a brandnew Laptop) or is it a bug in Thunderbird?

Best, Renate Albrecher

So many emails require me to scroll to the right to finish reading one line, back to the left for the next, etc. They hurt my head, they take fireever to read, and they hurt my right arm too. Thunderbird used to have an option to wrap messages, but it looks like it was deleted.

I tried adding the following tom my user css:

1. messagepane {

   margin-left: 45pt !important;
   max-width: 900px !important;
   margin-right: 45pt !important;

}

The margin-left works. It gives a spacer between the message pane and the folder list.

The max-width and margin-right don't work. The messages still require horizontal scrolling, and the scrollbar shifts left, right up against the text, so it doesn't give the needed spacer.

I use the spacers to avoid the parallax-induced migraines.

New laptop Win11.

Thunderbird installed and running, two differing ISP EMail addresses working.

Third address of four (fourth not yet tried) will not set, claims wrong user name/password.

This Email address (Sky as in Yahoo!) works perfectly on two other laptops under Outlook, it also works perfectly online from browser. So username/password is correct beyond doubt.

Possible complication (?) being while a Sky account address, login user name is an EMail for a different ISP's address. Did not have to do anything diff to basic login elsewhere though.

Ideas please?

Recently I have noticed some changes in the way my Thunderbird downloads POP3 messages. Previously, it would be common to ask for new messages once a day and receive upwards of one hundred of them. But in the last month, this number has been limited to about 35 at a time. If I ask immediately again, I get about 35 more, and this pattern continues as long as there are messages in queue waiting to be downloaded. I am not sure if this is due to changes in gmail, where most of my received messages originate, or to changes in Thunderbird itself, or to some sort of third-party hack. Now that I have trained myself to keep on asking until there are no more messages coming down, this change does not cause me much difficulty, although initially it sometimes caused me to overlook messages because I failed to keep asking as long as I should have. Apart from that, it does not seem to be harmful as far as I can tell. I'd just like to know if other people have noticed anything similar, and if anyone knows what is causing it, and whether it has some hidden advantages over the way things used to work.

bold textA little while ago, all of the messages coming into my Thunderbird app, do not expand graphics etc in the email. I just get strings of code and web stuff.. I cannot find the setting in my Thunderbird that will cause it to automatically translate all of these codes. Help please !
