How to change Firefox locale to ... esperanto?

Hello !

Today I felt the need to change the language of my Firefox browser to esperanto but I haven’t been able to do this, it is not straightforward…

First, you need to install your language pack, depending if you use the official Mozilla Firefox or Icecat, the rebranded firefox with non-free stuff removed

Then, open about:config in firefox, we will need to change 2 keys. Firefox needs to know that we don’t want to use our user’s locale as Firefox language and which language we want to set.

  • set intl.locale.matchOS to false
  • set general.useragent.locale to the language code you want (eo for esperanto)
  • restart firefox/icecat

you’re done ! Bonan tagon
