NILHello !

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

• link for Mozilla Firefox

• link for Icecat

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
