Using Firefox 49.02 auto detect of language does not work. I'm using Jaws and assumed it was a bad language tag before I turned auto detect of language off.

I have my OS and browser set to English and am browsing from a Dutch IP address. I get the Italian page. Not sure which part of "Accept-Language: en-US,en" (which Firefox sends) is unclear.

Edit: oh there is an English button in the right top. Only saw it just now (a flag might be more colorful to spot).

Using Chrome, getting Italian.
