Changing language of add-on

[Baptistou (Baptiste Thémine)]

One more question - can I implement switching language in my add-on if I’m using i18n? Because I don’t see any method to get a message in specified language or to set a different language.

I was also looking for a method to switch language with i18n. Maybe this discussion can help you :

Debug i18n internationalization

Hello, I am currently adding translations to my addon thanks to i18n and sometimes it requires some CSS adjustments because of the variation of phrase and word lengths. For now, if I want to switch the language, I have to rename subfolders inside _locales each time. Is there an easier way to switch between the different languages? An option to change inside Firefox settings or a variable to modify in JavaScript?
