In Thunderbird's Settings under "Language & fonts, Choose the languages used to display menus, messages, and notifications from Thunderbird" I have selected Danish and English. Now I would like to remove English, because my folder pane is displayed in English, even though I have selected Danish as the first language (I am from Denmark). But I cannot remove English in Settings, only move Danish or English up or down. I cannot click on the Remove check mark, neither for Danish nor English. Does anyone know why?

Hello, I’m unable to add additional email accounts on one of my PCs. I’ve tried everything — uninstalling and reinstalling Thunderbird, deleting cache files in AppData, but nothing works. The program keeps crashing every time.

Thank you in advance for your help, Alexis Lauxerrois

Bonjour, Je ne parviens pas à rajouter d'autres compte de messagerie sur un de mes pc. J'ai tout éssayé désinstallé réinstaller supprimé les fichiers caches dans AppData mais rien à faire ça plante tout le temps.

D'avance merci, Alexis Lauxerrois

I have noticed that quite a few emails have gotten into the junk folder despite the fact that they meet the criteria to be filtered by my own custom message filters and I have those filters set to run before junk classification. So it seems the junk filter is actually being applied prior to my own message filters. I'd really like to just turn off the junk filter entirely because I like to make my own filters to catch things that I deem as junk, (and that is how it worked on my old version of thunderbird that I had on my old laptop). Is it possible to turn it off, and if so, how?

If it is not possible, then it would be good if this apparent bug were fixed.

I included a screenshot showing just one example of an email from an address I had created a custom filter for in the junk mail folder.

HI and thanks for any help.. I am Popping my gmail and several other non-google accounts. It has worked for years but now I can't pop any gmail after 10/10/25. The mail is there when I go to the gmail web page. It is trying to Pop it cause I can see the message on Thunderbird "there are no messages to download" from that account. I checked and there are no filters. I did a test email. It shows up in gmail but won't pop to my PC. all the other non-gmail accounts are working fine with new messages coming in. I checked all the subfolders and nothing there since 10/10. Any ideas? Thanks. Kevin Brand

It appears Windows 11 KB5065797 broke my Thunderbird. It will not start normally nor will it start in safe mode.

- I've updated to latest version 144.0 - I've tried starting in safe mode - I've tried running as administrator - Thunderbird shows in Processes, and displays suspended randomly - I've restarted Windows - I've cleared cache under users\x\appdata\local\thunderbird\profiles\x\cache2\entries\

Hi I have just reloaded Thunderbird onto my laptop after installing a new hard drive. It worked Ok until i imported an account and now get this error message even if I uninstall and reinstall.

That appears in a box and thats it.

Cheers Jim

Hello. I accidentally made multiple copies of one folder and some of its nested folders. I can't move them back because the copy was already found in the main file. How do I remove the duplicates?

I tried to add a new account with PROTON mail and it didn't accept it. Can it be done? Is there a problem? The goal is to have 2 accounts and not just one. Can you fix it?

Something happened that took away my 'get messages' button and my 'write' button and the others that used to be there.

I can find nowhere to add these back. When I try to adde them back in view-toolbar-toolbar settings, 'SAVE' is greyed out.

Either I am a real dumb user or this is a real dumb bug that cropped up today.

I have no way to get messages or write one now.

Hi, I recently set up TB with one imap account. All fine. I set up a Local Folder as well - mainly to store bulk of old mails.

Then after couple of days, when I sent a message, the system warned me: "your message was sent, but a copy could not be placed in "Sent" folder" due to network or file access issues. Place a copy in local folder instead?"

I recognized, that also, while my account/server seems to connect, no emails at all are fetched from the server actually.

I think there's a strange problem TB internally with ... file access? How to repair?

UPDATE : I checked my TB profile folder, and found the "ImapMail" folder's properties (Win10) showed "read-only". So I closed TB, removed the "read-only" from folder and contents, and restarted TB. But issue persisted. I went back to "ImapMail" folder in my profile - and found it marked "read-only" again. So seems TB itself set it to "read-only", it seems.

Thank you for your advice. Chris

PS:

• Restart : nothing changed
• run in safe mode: nothing chnaged
• repaired folders: nothing chnaged

Hi all,

I cannot log in with a certain work account in Thunderbird any more, due to a failure that occurs during the OAuth process (error 530084).

While checking internally, we noted that the login information that Thunderbird is providing does not provide the Device Platform, state or identifier. I assume that this is data obfuscation done for privacy reasons but is there a way to disable it for on a device, specific account etc.?

Thank you for the assistance in this matter.

in the last couple of days thunderbird has stopped showing emails from one particular account. Inbox is only showing messages up to yesterday, and all mail is only showing to the day before (?). The messages are on the proton webmail inbox ok, and are received by the proton mail app on my phone. I have not changed any settings, and it worked perfectly before now

Hi, I found an entry in the "thunderbirdmail.de" forum from 2005, where they discuss the option of using userChrome.css for changing the number of lines in the title of an calender appointment.

My problem is, that if the text of the title is really long, thunderbird will not enlarge the title window (more lines), so I can see the whole text (as in Outlook - from where I just changed to Thunderbird a few weeks ago).

The entry into the userCrome.css (as suggested in the forum)

.calendar-color-box .event-name-label {

   white-space:  break-spaces !important;

}

is not working (even I changed the "toolkit.legacyUserProfileCustomizations.stylesheets" to "true").

Can you help me with that issue?
