Firefox (and I suspect other browsers) allow per-profile configuration of the language, independent of the OS. In the scenarios you describe, it's hard to see how geolocation makes things better, as it has all the same problems, except for the "installed in English because didn't change the default" where you now have a chance (but no guarantee) you'll select the correct language. And unlike configuring the language in the browser, there's no hope geolocation could even possibly work correctly. >In the idealized world that Silicon Valley imagines where 1 person uses 1 computer with 1 owner and speaks 1 language, it's fine. But in the real world, it's just a mess. In Silicon Valley geolocation works fine, but it's a terrible, terrible, TERRIBLE idea everywhere else.
