Hello, I am on the latest version of Thunderbird on a Windows 11 computer. Previously with a Windows 10 computer I had no problem spell checking e-mails in French. However with a new Windows 11 laptop the French dictionary although installed shows as not loaded on the dashboard and unsurprisingly does not function. I have restarted both Thunderbird and the laptop. No result. Any advice most welcome.

Best wishes,

Stephen Jefferson

hello I have bought with donation thundrbird, but is is in the wrong languange. I am installin g italian now, ant it asks me to contribute again. Can you reimburse the first payment thanks you laura bonanni

As you can see in the screenshot, the umlauts are missing in many emails. Unfortunately, the corresponding fonts can no longer be set in Thunderbird; I use version 140.6.0esr (32-bit). Where can I set that ä, ö, ü, ß (...) are displayed normally? Greetings from Berlin, Markus

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?

Hello Thunderbird supporters

This is a problem, because some faulty emails land in the folder "Junk", others in the folder "Spam". It is NOT possible to re-change these folders in german language. I don't know what's the cause for this changement - I didn't use a new source for my Thunderbird.

Thank you very much for your efforts

Kind regards Peter

Hello Frustrating.. I live in UK and want Thunderbird to work in English English but it keeps changing back to Canadian. I have been in settings and added English English and made it the default but TB keeps changing the setting and making Canadian the active language. How do I stop it?

TB 140.6.0esr (64-bit)

I am reporting an issue with message filters in Thunderbird.

When the UI language is set to Japanese (ja-JP), the “Perform these actions” section in Tools → Message Filters is not displayed, making it impossible to configure filters.

Environment OS: macOS Sequoia 15.6.1 UI language: Japanese (ja-JP)

After switching the UI language to English (US) and restarting Thunderbird, the actions list appears and filters work normally. Switching back to Japanese reproduces the issue.

This seems to be a Japanese localization-related bug.

Thank you.

Since today (Version 146.0 Windows11 64bit) all subfolders, which are configured to send emails from (e.g. name+test@example.com for folder test) are renamend to the german word "Gesendet" for Sent. You can see that in the second screenshot. In the first screenshot you can see the name "Gesendet" which is locked against changes and the normal name of the folder is support in this case. I don't know, what has changed to yesterday. And as I'm using this feature intensivly, the "Gesendet" over all folders is quite annoying.

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?

今日Thunderbirdのメーラーを開いたらメールフォルダが英字表記に変わっていました。 具体的には「受信トレイ」は日本語のままなのですが、「送信トレイ」が「Sent」になり「迷惑メール」が「Junk」に変わるといった感じです。 受信トレイ以外はすべて英字表記になっています。 設定にある「言語とフォント」は「日本語」のままで変更はありません。 元に戻す方法をご存じの方がいましたら、ご教示をお願いいたします。

Die Ordnernamen im POP3 Konto sind plötzlich englisch: Drafts statt Entwurf Templates statt Vorlagen Sent statt Gesendet Archives statt Archiv Trash statt Papierkorb. Wie kann man auf deutsch umstellen?
