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 far as I can tell from reading the help pages, the Firefox translation feature should automatically translate any page in any available language, unless explicitly set not to do so. However, I observe that no translation occurs unless I first select text, right click, and select translate, and even then, the translation is presented as unformatted text in a separate dialog box, which is not much better than copying and pasting web pages into some other translator service. Am I missing something here?

Sadly, this is not even close to being competitive with the Google Translate level of functionality. I use Google Translate every day to read package labels in grocery stores, road signs, and a host of other written sources of information. Occasionally, I even use it to hold conversations with people I would not otherwise be able to talk to. So far, I am nearly monolingual, and I am unwilling to do without this; I probably wouldn't travel if it were not available. It does tie me to that fraction of the surface area of the earth where high speed internet access is generally available, but I don't really need to go any places where it is not; I am not trying to hike across Antarctica. I understand that there is a loss of privacy when dealing with Google, but I do whatever I can to fend that off, and the value of the free services I receive in exchange is huge. What's the future of Firefox in this respect?

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 previously posted this question: https://support.mozilla.org/en-US/questions/1495577

Asking how to use the "intl.accept_languages" setting within the JSON for the new preferences setting within group policy.

A moderator posted this as a comment which I have only just noticed: "The value is a string, so it has to be in quotes "en-GB"" - the post is now too old for me to reply.

I'm still having issues using this setting even after putting the name in quotes. I've tried:

"intl.accept_languages": { "Value": "en-GB", "Status": "user" }

"intl.accept.languages": { "Value": "en-GB", "Status": "user" }

But neither work, please can someone clarify what exactly needs to be used within the JSON?

I am using Firefox 128.5.0esr (64-bit) on Debian 12. This is the browser that comes installed with the system. Recently, an offline translation feature was added to Firefox. In settings, you can download various languages. I would like to know where language models for offline translation are stored. The downloaded languages I want to copy to another computer without internet connection so that I can use the offline translation on this computer.

Yahoo Mail settings. When I use Yahoo Mail with Thunderbird for Android, the folder structure is displayed in English. I want everything to be shown in German. Everything works correctly with Gmail; this is only a problem with Yahoo Mail. I've set everything to German in my Yahoo account, but it's still displayed in English in the app.

What can I do?

Firefox’s built-in translation feature actively gets in the user’s way.

When translation is actually needed, it often does not offer the translation function at all.

Google sometimes links to Reddit pages that have been automatically translated into Korean by AI.

https://www.reddit.com/r/firefox/comments/1om0x4d/reddit_on_firefox_is_just_straight_up_broken/?tl=ko

That specific page appears in Korean, but when you go back to the Reddit homepage, it appears in English.

However, Firefox’s built-in translator still recognizes the site as a Korean website.

Even though all the page content is in English, the translator incorrectly offers the option “Korean → English” instead of the correct direction.

There needs to be a shortcut or option that always translates “English → Korean” when the user wants it.

Firefox should not decide when to translate or which language to translate. That choice should belong to the user.

Additionally, a dedicated keyboard shortcut for translation is needed.

I used the built-in translator for a while, but the inconvenience became so significant that I gave up and reinstalled a translation add-on.

Is this the right place to post this suggestion?

I travel a lot and frequently use web services not in my native English. Safari does a great job of translating to English, but is often glitchy for other functions. So I use Firefox. But it doesn’t have the translate option!

I don't know why, but when I browse pages in English, the context menu offers to "translate selection into Hebrew". This is weird and totally unwanted. I don't know how FF decided that I need translations, and specifically to Hebrew!

In the settings, my preferred language is "English (US)". In "translation settings", the list of "Translation will happen automatically for the following languages" is empty, and the list of "Translation will not be offered for the following languages" has Hebrew and French. (I would add English but I don't see how.)

Is there a way to just remove this translation option from the context menu?

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?
