Thunderbird Community Forum

I've (finally!) managed to set up a new account on my new PC (having found the required password, a long string of letters - where did that come from? - I would certainly never have chosen that and I was never informed of it). I also successfully managed to transfer my Profile from the old PC to the new one (thanks to your helpful article. However, While I have thousands of 'sent' messages I only have a few in my inbox and sub-folders (i.e. today's). (I originally used the recommended server settings (?IMAP) I was offered but then changed to SMTP/POP which is what I always used before without problems.) So - I go to 'Import from a Thunderbird profile' and it shows me the Profile Name and Directory details, but then says 'Nothing can be imported from the selected source' - but doesn't tell me why not, nor what I should do about it! Given the Profile has transferred successfully, why can't it be accessed? Any ideas appreciated. Thanks, David Collins.

Hi, I'm following up on this thread which is closed- https://support.mozilla.org/bm/questions/1483264 It describes an add-on: "DefaultColumns" https://www.ggbs.de/extensions/#dc. I could not find verification of safety for this add-on. I reluctantly installed but it wants permission to my whole computer so I uninstalled.

To me, this functionality is a necessary feature needed in Thunderbird. It merely creates default columns for all new subfolders. Could someone verify the safety of this add-on, recommend a safe option or add the functionality to Thunderbird. Thanks.

1. I've drafted an email, then hit save / closed the email and opted to "save changes". 2. I try to edit that email, but it is just "flashing" in the preview screen. I right click on it to "edit draft message", but that just brings up a blank email. 3. The status in the bottom left of the screen shows "loading message..." "downloading message", repeatedly. 4. It was working fine earlier in the week, but Thunderbird Desktop Version 140.7.0esr | Released January 13, 2026, seems to be when the problem started?

Thunderbird has suddenly started autocorrecting a particular word in my emails. I type the word "Ronnie" a lot and for no apparent reason, a window with "Rog" and an X comes up and it autocorrects to "Rognie" - see attached screenshots.

I've looked online and someone suggested it could be something to do with my address book but it happens when I am composing the email itself.

My name is Roger and I sometimes sign off emails "Rog" but this autocorrection has only just started happening and I can get rid of it.

AnMoS Tahoe 26.2y ideas, anyone?

Just installed TB 147 under Windows.

Previously, there was a menu item File/Compact Folders (plural).

It is now (at least on my machine) replaced with File/Compact Folder (singular), which only compacts the currently active folder. I cannot now find a way to compact all folders at once.

What am I missing?

I have Thunderbird on my Omen 35L on Win 11. Thunderbird CANNOT CONNECT to Comcast to send an email. This was not a problem on Win10. I have done ALL the settings fixes and NOTHING WORKS. Other mail provider accounts send OK (e.g. Site Ground). This is unique to Win 11 and Comcast.

Hello, I am using TB 140.7.0esr. I have five email accounts in TB and all send emails but one. This one email receives IMAP emails, but will not send. All emails accounts are hosted on Godaddy Office 365. The one I am having issues keeps popping up the dialog box to enter password when sending. When I click on the button to add a new passoword, TB just tries sending again. It never shows the popup to enter the new password. I have deleted this account and installed new, still same issue, only on this one email acount.

Thank you, JR

Seit kurzem, ich glaube seit dem letzten Update, werden mir Anhänge (in meinem Fall automatisch hinzugefügte Anhänge von WISO Mein Büro) immer mit dem Namen des Pfades verschickt, wo die Datei vorübergehend gespeichert wird. Fürher hat es immer einen kurzen Namen (Rechnung Nr. XY) genommen. Ist das jetzt ein Problem von Thunderbird oder WISO? Kennt jemand das Problem?

Hi, I am trying to export a calendar from a Windows 10 PC into a Lubuntu PC. The exported Home.ics file is about 217KB. At stage 4 in the import process (which shows the file name correctly) a message in red says "No importable items found in the file" . In the main area it says "Loading items" but nothing happens. Am I missing something here? Thanks

Why did retrieving messages suddenly stop. It was working yesterday and I made no changes to anything. I can send successfully. I am using Shaw/Rogers Pop server.

Why does "test connection to server" fail?

I've recently installed Thunderbird and configured it to connect to a few of the email accounts I've setup. For gmail servers, everything seems to work fine. For a locally run hMailServer server, I can connect, download messages, and even send messages - sort of.

When I try to send an email through the hMailServer account, the message sends correctly: it arrives at the other address quite quickly, and I can see in the server's logs where it connected via SMTP, transmitted the message, received a "250 Queued" response, sent QUIT to log off, and got the "221 goodbye". However the Thunderbird UI itself never progresses past the Sending Message dialog: the status stays at Sending message... and the progress bar is full. I can hit cancel and it prompts to delete the draft, etc., but either way, the message has been successfully sent. This doesn't happen with other accounts, so I'm curious what I need to do to get this to go away or send correctly....

I'm using Thunderbird 147.

I use Thunderbird 115.18.0 on a Windows 7 machine. I wish to transfer all my Thunderbird data to a machine running Linux Mint 21.3 which has Thunderbird 128.12.0esr. I have not been successful after many tries. Could this be because the Thunderbird revisions are different? If so, can I get 115.18.0 to install on my Mint machine? If not how should I proceed? I have already tried creating a new .thunderbird directory with ********.default directory from the other machine. I have also tried a new .thunderbird directory with a the ********default-release directory as directed by one site.

I have the same original problem as https://support.mozilla.org/en-US/questions/1508740 , and from the same time period, but across 4 of 5 email addresses, with additional problems. All given answers then & now on this website have completely failed me.

I have 4 emails on the same server, which use IMAP, so there is no way for me to adjust any msg retrieval settings, because they don't exist. Surprisingly, one of these 4 emails actually does work in sending & receiving, but I got different error with it, just now! I also have one gmail affected by this original 2 year old problem, as well.

Closing program, restarting computer, and downloading TB updates all do not work. I uninstalled/reinstalled TB, and all of my profiles & emails were surprisingly intact with no deletes (yes, I backed them up in another folder first), and the problem persists upon reinstall of TB, on the exact same emails as the original problem. Antivirus & firewalls are off. Server said it wasn't them. I'm using Windows 11, McAfee antivirus, and the newest TB dld is Eclipse.

There is no distinct alphanumeric error message for the oldest problem, just the usual "Login to server with username failed. Retry/Enter New Password/Cancel." All passwords are correct. None of my passwords are "saved" in the TB program, and I'm having trouble locating where to tell it to do otherwise.

Screencap and copy/paste attempts to grab second error message failed, but it looked like "RETR failed, one message expunged." So far, it's a one-time error, which I can live with. All emails for that ONE working email are fine.

When I attempt to sign into Google, it takes me to a troubleshooting page https://support.google.com/accounts/answer/32050?hl=en asking me to clear cache & cookies, if I'm using Chrome (which I'm not), instead of just a login to retrieve my gmail.

My emails have been sitting on the servers for 2 YEARS and I am at my wits' end - please help!!!

I just started having a issue where it will be for example noon , and I just get a email , that is not on top but down the list and it says 9am , or similar times where it is 1 or more hours later from the time on the email , but it just showed up , but its down on the list of recent emails , so for example I check emails and a few come in or I get a notice that I have a new email

I have Thunderbird minimized in the taskbar , I never close it , and it will show a email from a few hours ago that just came in , but its below emails that I have already read that were after that time , so basically its like some emails just randomly appear that didn't get delivered when they were supposed to along with the others at that time , this is not a 1 time thing , this has happend several times over the last few days

I can't find any Setting that allows me to choose Newest Emails on Top , or to check the Time to see if it thinks its a different time of day than it is when delivering , or to bring in emails in order of delivery time , newest first and so on , so if a email has a Delivery time of 9:38 am I actually recieve it at 9:38 am , for example I got a email showing the time at 12:48 PM as delivered (10 minutes ago , but I just got the email now at 12:58 am) , then I got one time stamped at 11:15am , and 11:13 am , and at 9:38 am , , the 9:38 am email came AFTER I got the 11:15 email by about 30 minutes , and the one I just now got (it was 12:58pm when I got it , but it shows a time of 12:48 pm so 10 minutes difference from the time it shows delivered to the time I actually got it) , this is while my email is open and I am looking at emails ..... Email Version .. 147.0 ..

Any Ideas ??? .... Thanks .... Jim

Thunderbird downloads from Gmail (a POP server) spam folder. It should only download from the "Inbox", isn't this correct? Gmail is not IMAP, which would dl all folders? Downloaded phishing and spam emails which come from the Gmail spam folder always have an incorrect time stamp.

Hey. New to Thunderbird. I am using the Linux version. I have a couple annoyances I'm sure are configurable, but I can't figure out. FYI, using IMAP and unified folders.

1) I'm watching mail retrieval in the status bar. Seems very one mailbox at a time rather than all at once making mail retrieval much slower than something like Apple Mail. Can that be changed to all at once?

2) This one really irks me :) I'm sitting in the trash folder and right click on it to empty it. It shows it does empty in the status bar, but the messages are still showing in the trash folder. If I click on another folder then back on the trash folder it shows empty. Why does it not refresh to show the current state of the mail folder?

Hello, My SMTP server uses Let's Encrypt certificate. The website with the same domain has no certificate. Thunderbird refuses to connect to my SMTP server. Test connection to the server (STARTTLS) in account settings sais "The secure connection to the server failed" (or similar. I see bg localization). Another server with Let's Encrypt certificate. Test pases. Clicking View certificate shows webserver cert (from DigiCert Inc).

I can't send emails! :)
