I get messages, questions and info from Firefox in Dutch. My language preferences in setting is English UK across the board. Browser, preferred, fall back and web site language. It works most of the time, apart from with Firefox. What can I do to make Firefox talk English to me?

I use to have spell check on my Mac Air, but now it's gone. How do I get it back on? I've googled to find out, tells me to go to Settings, Language, etc. Spell check shows it's mark in the box, but when I go to type in words it doesn't come underlined in red. How can I get it back?

Thank you in advance!

In my Settings, the browser's fallback language is set to Portuguese, without giving me any other language choice, nor leaving it blank. I assume this is the reason I keep seeing menus, notifications, etc., randomly popping up in Portuguese.

Hello,

My Firefox interface is set to Ukrainian, and everything in the browser is displayed in Ukrainian. However, when Firefox shows a notification about an available update, the text of this notification is in russian.

I do not know russian and have never selected it anywhere in Firefox or in my operating system. I would also like to explain why this matters to me: seeing russian in my browser is genuinely unpleasant, because russia is waging a terrorist and aggressive war against Ukraine. For many Ukrainians, software defaulting to russian is not a minor localization glitch. It is something we actively want to avoid.

Why does this happen, and how can I make sure update notifications appear in Ukrainian?

System details: – Firefox version: 156.0.1 – Operating system: Windows 11 – Where I downloaded Firefox: mozilla.org

A screenshot of the notification is attached.

Thank you for your help!

When using the native translation tool in Firefox for iOS to translate an English page (specifically tested on Wikipedia) into Portuguese, the translation is incomplete and inconsistent.

This behavior mostly occurs inside collapsible sections (the topics that expand and collapse when you tap the arrow icon). The translation failure is not just on a paragraph-by-paragraph basis; it often occurs partially within the same section, where some sentences are successfully translated while others right next to them remain entirely in English.

Ios 18.7.8(22H352) Firefox 152.4(74210)

Steps to reproduce:

   Open Firefox on iOS.

   Navigate to an English Wikipedia article (mobile view, which uses collapsible sections).

   Trigger the built-in Firefox translator to translate the page to Portuguese.

   Expand one of the sections using the dropdown arrow.

Expected result:

The entire text, including all sentences and paragraphs inside the expanded sections, should be fully translated into Portuguese.

Actual result:

A broken, partially translated layout where some sentences/paragraphs are translated, but others immediately below (or within the same block) remain in the original English.

(Note: Please attach your screenshot showing the open section with the arrow and the mix of Portuguese and English text).

Hi First of all thanks a lot Mozilla team for creating a wonderful master piece of security and privacy. I really love firefox browser native translation feature. By unfortunately my native language still missing. I am still surprised why urdu still not added as language in translation. There are arround 500 millions native urdu speaker's Please support urdu Also.

I speak more than one language and want to have transparency and control of the content. Therefore I always want to see any website in it's native language first.

My preferred situation then would be to have a menu in the tab where I may choose a translation. In the case of a multi-lingual site I want to have those languages as additional options on top - with an indicator for the sites default language. So I may first choose the sites language, then (possibly) into which that is translated into.

But at present I can use only the settings of preferred language for multi-lingual sites, never knowing what language was the base for the content. (Presumably the most accurate content of the website.) And I can add languages for translation and sort them, while - weirdly - I cannot delete them later as there's no control element for getting rid of (maybe accidentally) downloaded ones.

Is there a solution already? Did I miss something in the settings? And: Where is the „translation panel“ to which the settings „Translations - More translation settings“ refer to in the block „Never translate these sites“?

I recently move to a new Windows 11 computer and seemed to have done the move correctly, given that everything showed up, and I could send and receive emails.

For no apparent reason, however, the keyboard suddenly began mistyping in the message portion of the email message frame but not in the header ("To," "Subject," etc.) areas. For example, when pressed, z appears as {, y as z, h as i (but followed by a space), 6 as 7, d as e, and so on.

I tried various fixes, which didn't work, such as pressing windows key + space bar simultaneously, or left alt + space bar simultaneously, to no effect at all: nothing appeared, nothing happened. I looked in "Settings" to see if there were any other keyboards listed, which there weren't.

This is happening nowhere else, in any other application, but here, and I've never seen anything like it before. Also, I've used Thunderbird for quite awhile and never saw nor heard of anything like this.

I sure could use some help. Thanks.

Hello everyone.

Lately a get my emails from greek senders like in the screenshot, not everyone, but most of them. I tried many things like, changing mime variable from false to true, removing addons, repair folder, repair font to no avail. I also disabled antivirus. The questios marks are also in the "ctrl+U" screen and the fonts looks utf-8 as normal in the header. They look normal online or the yahoo mail app in iOS. Anyong knows how to fix this?

Thanks in regard.

Whenever Firefox offers or I request a translation it always, without fail, offers Estonian as the destination language.

I deleted all the languages from the app (or whatever) and just downloaded the ones I require but that made no difference.

Hello Mozilla Support,

I'm experiencing an issue with how Firefox displays date and time input fields on websites when using Hebrew (Israel).

• • Environment:**

- Firefox version: 158.0 (64-bit) - Operating system: Windows - Browser interface language: Hebrew - Regional locale: he-IL

• • The problem:**

Date fields are displayed in the format YYYY.MM.DD (for example, 2026.10.14) instead of DD/MM/YYYY (14/10/2026).

Time fields also sometimes display their components in an incorrect order, apparently due to right-to-left (RTL) handling.

This issue occurs across multiple websites, including the standard HTML date input example on MDN, so it is not specific to any particular website.

• • Troubleshooting already performed:**

1. Verified Windows regional settings: Hebrew (Israel), short date format dd/MM/yyyy, and time format HH:mm. 2. Verified Firefox regional preferences show he-IL. 3. Tested intl.regional_prefs.use_os_locales with both true and false. 4. Tested intl.locale.requested with he,en-US, he-IL,en-US, and he-IL. 5. Changed the preferred website language order to prioritize he-IL. 6. Restarted Firefox after making changes.

Unfortunately, the date issue persists, and the time field display is also inconsistent.

• • Expected behavior:**

Date fields should display DD/MM/YYYY, and time fields should display HH:mm in the correct visual order, while keeping the Firefox interface in Hebrew.

Could you please confirm whether this is a known Firefox bug and whether there is a supported workaround or a planned fix?

Thank you.

Firefox shows Russian as the selected "Fallback language", but I cannot change it to another language.

My current language settings are:

Preferred language: English (US) Fallback language: Russian Website languages: Ukrainian [uk], English (United States) [en-us], English [en]

I do not want Russian to be used as a fallback language.

Steps to reproduce: Open Firefox Settings. Open the language settings. Set the Preferred language to English (US). Observe the Fallback language setting. Try to change the Fallback language from Russian to English or Ukrainian.

Actual result The Fallback language is set to Russian and cannot be changed to another language. The fallback language dropdown works correctly, but the list contains only Russian.

Expected result

The Fallback language should be selectable independently of the Preferred language, and I should be able to select English (US) or Ukrainian or Polish instead of Russian.

Additional information

The issue is present on:

Firefox 154.0.1 macOS Apple Silicon (aarch64)

The Website languages setting already contains Ukrainian and English, but this does not allow me to remove Russian from the Firefox UI fallback language.

I'm getting the "whats new" page always in Russian

Your 'translate page' is NOT working efficiently anymore on my desktop and it is impossible to get work done now I go to my phone, and you've rearranged everything and I can't find it there Firefox is becoming a burden. I left a google review and it tells me to come here... 3 days and 6 pages later I found where I can ask for help and not get an 'article' from 2023 Ridiculous

I am currently using the Vietnamese Telex IME of Windows 11 and I just found out that whenever I type the "." after any word, that word will be deleted. This is how to recreate the bug: 1. Type "hello " 2. Backspace (delete) 1 time, now it is "hello" 3. Type "." and the whole thing is deleted, turned into an "." string instead of "hello."

I just wanna ask if there is any setting or config that can solve this problem. Thanks.
