I-Thunderbird Community Forum

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。

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

I am using Thunderbird with IMAP accounts and the Swedish language pack. My Inbox is correctly displayed as "Inkorgen", but other system folders like "Drafts" still show their English names instead of the Swedish ones (e.g. "Utkast").

In the folder properties dialog, it looks like there is a field for the display name separate from the server path, but I cannot edit it for system folders. For custom folders I can rename them, but not for Drafts, Sent, or Trash.

Is there a way to change only the display name of these system folders without altering the IMAP path? Or is this a limitation in Thunderbird's localization/mapping?

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?

Dear Support Team,

I am writing to report an issue with the folder names in your program.

Although I have selected Polish as the primary language setting within the application, the names of system folders (such as Inbox, Sent Items, Drafts, etc.) are all displayed in English.

Crucially, on my original mailbox (accessible via webmail or other clients), these folder names are correctly displayed in Polish.

I have attempted to change these folder names manually within your application, but the changes do not persist, and the names revert back to English. There seems to be no other option within the app to correctly synchronize or change the display language for these folders to Polish.

Could you please investigate this issue and provide a solution to ensure the folder names are displayed in Polish, consistent with my language setting and original mailbox configuration?

Thank you for your time and assistance.

Sincerely, Szymon

Bonjour, Après plusieurs essais je n'arrive pas à mettre les dossiers de mes comptes mails en Francais ? ceux-ci restent tels que: - Drafts, - Sent, - Junk, - Trash. Par contre le dossier "Courrier entrant" est bien en Francais. Dans les paramêtres impossible de les changer. Merci de votre aide.

I dropped by to see if I replies to a query about Thunderbird. Sometimes the options to Login wouldn't let me in, it kept going to "Como colaborar" that went to a Page with mixed English and Portuguese, another page had mixed Spanish, Portuguese and English.

After a lot of translating, I made it my login. Wow! And my day has just begun. :) ~r

My Thunderbird calendar refuses to display dates in European format, namely day-month-year. I have read lots of helpful hints on the forums and tried everything, but nothing changes. My system is Ubuntu 25.04 with Cinnamon 6.4.8. Thunderbird version is 140.3.0esr (64-bit). Some of the suggestions refer to settings that are no longer there compared to earlier versions. For example, Settings > General > Language and Fonts has no format options. I have also used the config editor while TB was not running and added ntl.date_time.pattern_override.date_short and ntl.date_time.pattern_override.time_short, without any effect. Dates in the calendar still always appear in the illogical American month-day-year format. This is confusing, to say the least ! Has a solution been found to EASILY select the locale and formats that should be used? At the moment, the settings are under different menus and in different locations, and TB seems to be making it as difficult as possible to get these set - permanently ! - to the user's preference.

Bonjour suite à une mise à jour de Thunderbird en date du 17 octobre le nom de mes dossiers est maintenant en anglais. J'aimerai bien savoir comment faire pour les remettree en français. Exemple Trash comment le renommer corbeille. Merci pouir votre aide

I'm using Thunderbird in Polish language. After upgrade to ver. 144.0.1 folder names for my only IMAP account have changed into English and fonts into capital (except inbox folder name). Attached screenshot shows discribed case in red frame - capital names are in Engliś and inbox is in Polish. Below in green frame there is my POP account and folder names are correct.

I was looking for a Finnish spell checker, but apparently there is none. The issue appears to be that a dictionary is far from enough for checking Finnish as the endings embedded into words do the trick prepositions do in many languages (i.e. house - talo, to the house - taloon, from the house - talosta, from my house - talostani). There is a spell checker engine available (Voikko), but the WebExtension API fundamentally doesn't provide the needed support. Likely LLM helpers will have the same issue.

Questions: Is my understanding correct? Is there any plans that this could be fixed ? Any tricks that could be applied ? i.e. old enough version as it used to work for long time a ago?

If my understanding is correct, then it doesn't make sense to have Finnish language SW-version and downloading page. At least without proper warning that this important feature is not available.

I occasionally create a message in right-to-left language. I can allign the text right, for that purpose, but I cannot enter text in the regular "flowing" manner as left to right english text. The cursor keeps on jumping to the beginning of the line, and the period is added at the beginning of the right-to-left text. Finally I realized that this is because the allignment is set properly to "right", but I cannot find a way to change the PARAGRAPH DIRECTION, which remains left-to-right! Typically, text entry programs provide an allignment as well as a Paragraph Direction setting for right-to-left languages. Any knowledge of how to set right-to-left paragraph direction will be greatly appreciated! Thanks much!

I have Thunderbird 144 and i have problem. I add pop3 account. New clean instalation Thunderbird. The name of Inbox is in Slovak "Doručená pošta" This is ok. Other folder have bad names. Not in Slovak but in English. Older versions Thunderbird not have this problem. Version 140 is ok. When I upgrade version 140 to 144 problem is here.... What about that?

Incoming mail (txt only; no html) is getting more and more unreadable the last weeks. It looks like in the attached screenshot. I am desperate. What can be the cause of this?

At the same time there are problems with outgoing mail. Characters like 9 or : do not appear on screen although I typed them. When I copy the text to another program, these characters do show. Very annoying. Hope there is a solution to be found somewhere!

Best, Mike

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.

Need support for multi-language support for folder settings:

I am using Thunderbird(EN) as email client to retrieve emails outlook server in German(DE).

Yet the SENT folder there named "Gesendete Elements" in German. This makes the sent emails placed in 2 different folders, same as other folders (e.g. Draft, outgoing...), i.e.: Emails sent from iPhone can be found in German "Gesendete Elemente", Emails sent from Thunderbird(macOS) placed in "Sent", In Thunderbird(macOS) I no folder of "Gesendete Elemente" under this account.

I tried the troubeshooting method at Microsoft/Outlook: ["https://learn.microsoft.com/en-us/troubleshoot/outlook/user-interface/incorrect-folder-names" | trouble-shooting method at Microsoft] ,

Not working. Hereby macOS native mail client has no issue as well as iPhone. So that must be a issue of Thunderbird. Please help.

How to fuse/ auto designate the "Gesendete Elemente" as SENT etc. ?
