Since yesterday my Firefox thinks that everyone in Belgium speaks Flemish. This is a typically American problem: Americans NEVER seem to know where languages are spoken (I think they just guess), but for some reason believe that language localization software is cool.
It is NOT; it is a curse. So suddenly I no longer have my user interface in English (which was fine), but now in Flemish, which looks and reads like a tongue disease and is not even the second language of the area I live in (the first language here is German and second is French). How can I change back to English?
