Clarification: since Lithuanian is not that popular in the world - all the pages show in russian language by default (even Mozilla itself). Not english. Only old people remember russian.

Hi,

To manage this list:

1. Click the menu button and select Settings.
2. In the General panel, go down to Language.
3. Click Choose next to Choose your preferred language for displaying pages.
4. In the popup:
   • Use Add to select more languages
   • Use Remove to delete unwanted entries
   • Use Move Up / Move Down to change priority
5. Click OK.

   

For computers in a domain, you can use the RequestedLocales group policy.

Should I report a bug about default language set for LT, what do you think?

russian is an obvious choice for removal, but still there's about 100k russian babushkas in Lithuania.

Huh. So I asked about this a few times, in terms of what's acceptable and politically alright, and, well, just plain sensitive… for some other regions. These defaults, as in what a locale ships for some default prefs in the browser, actually comes from the localization volunteer community itself:

https://github.com/mozilla-l10n/firefox-l10n/blob/b4b8115a/lt/toolkit/chrome/global/intl.properties#L23

(For this particular entry I was not able to track back where the decision happened, as I got lost in the history logs about two decades back…)

The good thing is that you can just easily reach out to your local community: https://pontoon.mozilla.org/lt/firefox/team-info/ and discuss changing this value: https://pontoon.mozilla.org/lt/firefox/toolkit/chrome/global/intl.properties/?string=81017

I do remember half or one year ago of that list consisting of only Lithuanian and English. Either that or im using the good thing everyone is after. My point I guess would be: russian babushkas are using russian localized version anyway. Same with Polish people.

Is this the question of what shows up if theres no translation to a default (Lithuanian) language? Is English or russian more fitting to act as a fallback. Right now most 44y-olds dont speak or understand russian. Looks like these are the questions i should be asking a localization volunteer community.

Thank you both TyDraniu and jbr for your time spent and good advices. I did not expect this to be that fast honestly.

What however definitely sounds like a bug, is the priority/ordering ("quality value"), as the localized pref definition apparently places English before Polish or Russian — so this was only ever intended as a "catch–all" for cases when no native, and no English content negotiation would provide results, but some Polish or Russian content would be available (as weird that assumption may sound).

From your report it sounds that the lack of mozilla.org/lt wouldn't pick mozilla.org/en-US for you but mozilla.org/ru ~ which… is not the expected order:/

Could you share both the header and the table that this page https://manytools.org/http-html-text/browser-language/ shows if you visit it from a browser still in "factory settings" in your locale? Appreciate it!

(Double post, sorry for that)

Sure! https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-05-30-13-40-16-36af5e.png

At first i thought "winget install mozilla.firefox.lt" was at fault. Yet official download (on a separate install) gets me the same thing: https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-05-30-13-40-13-5f958f.png

Wow okay thanks — I just wanted to confirm it's the same order on the common release and when installed on the local OS. (As I can see the same result on a Nightly with the langpack baked in, running en-US unlocalized OS.)

This is however totally puzzling, because, well while somewhat specific, if you look at the localized prefs: https://pontoon.mozilla.org/entities/81017/ (where most have en-US/en as the ultimate fallback, so if there's some dedupe or hoisting/reordering going on, other teams would not notice…) — there's also a similar example: Silezian — and guess what? Their order of German being after English is… honored correctly: (how comes it works for one list, but not another?)
