[Bug 867753] Re: Accept-Language header contains incorrect value

[Phill]

** Description changed:

  Both my OS and Firefox preferences has en-GB and en as the language,
  however, it's sending "en-US, en" in the "accept-language" request
  header. This was verified using Bugzilla after finding the problem.
  Dates on some sites are a particular problem given that for many dates
  there is no way to tell the difference between en-GB and en-US, you just
  read the date wrong.
+ 
+ Steps to reproduce:
+ 1) Start Firefox
+ 2) In Edit -> Preferences - check the lanugage settings are "en-gb" and "en".
+ 3) Start Firebug.
+ 4) Access www.google.co.uk
+ 5) Check the "Net" tab in firebug.
+ 6) Expand the first (or any line).
+ 7) Scroll to the "Request Headers".
+ 8) Observe "Accept-language" contains "en-us,en;q=0.5".
