I-Thunderbird Community Forum

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.

OK, so I have 4 different emails on my Thunderbird account. I get the most email from my usa.net (Netaddress.com) account, but that has never been an issue -- as my inbox gets huge I just move the contents into a dated archive.

I have already looped back to the people at usa.net and all of my settings are correct.

Here is the issue: Out of nowhere, a few months ago, when I tried to download my USA.net email, it would stop after 100-200 emails. Also, it would NOT "register back" to USA.net and show the downloaded items as "gone" (I checked my settings; I am NOT leaving email on the USA.net server).

I even tried deleting a ton of emails on the USA.net server side via webmail, and it still just stops after 200 messages max. I then need to dump out what was downloaded to another folder or I get the error below (see upload).

I hadn't changed anything on my settings when this started. USA.net DID start a requirement several months ago RE using SSL, but I didn't have problems when I initially made the switch.

Help, please! When it stops downloading I either get no message, or I sometimes get the message shown.

How to fix please? Again, this is the ONLY email account that I have this problem with; if some kind of "limit" was being hit it wouldn't be letting me download from other accounts, including my "business" email (basically I use USA.net for all of my newsletters, online purchases, etc).

Thanks so much.

There is no immediate delete "trash can" in the message card view. Why?

Many messages can be deleted as you view them in the card. Additional steps, such as highlight-delete or clicking the dots and then deleting, are extra steps that are not only inefficient but also extremely annoying.

Can this be fixed, or is there a step I have missed to add a trash can to the card display?

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

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.

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.

On the 20, of October I was forced to re install Windows 10. Kept my data but I had to re install all my apps. With Thunderbird I follow the same procedure I used with Firefox: After installation I copied the profile folder from my backup and replaced the new one. That worked out well. With Thunderbird, I followed the same procedure, all my emails where there but not my local folders. I am attaching several snapshots to illustrate my steps. Image 1 "local folders now" Image 2 "Profile Folder". (why there are 2 sub-folders)? Image 3 "Mail in the profile folder" Image 4 " List of folders in my Local Folders" The are there, how do I get them back on Thunderbird in the correct place "Local Folders"? Thank you for your help again. Regards Ilio Pieroni

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.

I have been reading the posts re this problem; there have been quite a few. Ever since I updated to Win11 (a week ago) and installed the latest version of Thunderbird, I have not had any option to allow external content in my emails. There used to be a yellow bar above the email body with an "options" button. There isn't now. I have tried checking "allow eternal content in messages" in the settings; no change.

There was a suggestion to work around this by pointing at the message and choosing "unencrypt email and copy to...(choose folder)" from the popup menu, and then read the unencrypted message in that folder. The menu I got only had "copy email link" and left me to decide what to do with it. A newsletter in HTML is very hard to read. I don't want to work that hard.

Others with this problem were using Bitdefender, and you seem to have concluded that this was a problem with Bitdefender and doesn't need any further help from Thunderbird. I do not use Bitdefender. I hope you will change your minds and address the problem. I liked Thunderbird before, and now it's turgid and hard to use. Should I downgrade to an older version? If so, please tell me how.

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 cannot often download emails via a hotspot. Sometimes one or two will come, then it will just stop. I get two different error messages. Most of the time I start with the "Home folder is being processed," then it will refuse to write to the disk. I have no issues at home or on wifi, only with a hotspot connection.

Since we frequently camp where there is no internet, this is a bit of a bother. This is xfinity email over a tmobile hotspot. Thanks for any hints.

when attempting to sign into email account keep getting "Login to server IMAP.Shaw.ca with username scolling Failed" error message. tried clearing cache deleting shaw account and reinstalling but cannot get email account back as keeps getting error messages

Some time back I learned that going to config and changing "mail.delete" from FALSE to TRUE would change the way deletion worked so that after deleting a message the cursor would move to the next most recent message instead of the subsequent one. I've now decided that indeed I preferred the default setting of FALSE. I have changed it back on my two PCs, both running Win11 24H2 and TBird 128.14. On one PC the direction was changed back to the default direction, i.e. go to the subsequent message. On the other one it still moves to the prior message. I think I have done exactly the same thing on both PCs. What do you think I might be doing wrong?

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.
