- My browser language is set to Canadian English, UK English, or US English, depending on which browser supports which language pack.
- I’m located in Switzerland.
This leads to all sorts of annoying web site behaviour
- I get ads in German.
- Worse, I get web sites that assume I want the German version. Please sniff my browser language for that, not my location.
- Air Berlin’s site assumes I’m in the UK and prefer English based on my language settings. OK. But I’m not in the UK, I’m in Switzerland. I change my location to Switzerland, and the list of preferred languages is restricted to German, French, and Italian. <sigh />

That’s cool. I didn’t know that browsers had language and country settings…
