Comment (by mcs):

 There is some documentation here: https://developer.mozilla.org/en-
 US/docs/Web/Events/languagechange

 I assume that the only way to trigger this is to change
 `intl.accept_languages` (either via about:config or via the preferences
 UI). I wonder how many pages listen for this event. It might be okay to
 just suppress it.
