[Bug 643899] Re: Firefox sending header "Accept-Language: chrome://global/locale/intl.properties"

[Chris Coulson]

** Description changed:

  Binary package hint: firefox
  
  Upgraded from Lucid to Maverick a bit ago, and now a recent update has
  caused Firefox to start sending the wrong Accept-Language header.
  Couldn't find an existing bug report, but I see it was discussed on the
  forums: http://ubuntuforums.org/showthread.php?t=1536811
  
- ProblemType: Bug
- DistroRelease: Ubuntu 10.10
+ *** TEST CASE FOR SRU ***
+ 
+ As the original bug isn't easily reproducible, it isn't possible to
+ verify with 100% confidence that the update fixes the actual bug.
+ However, we can test with 100% confidence the bug which we *think* is
+ causing this bug here.
+ 
+ To prepare for this:
+ 
+ 1) Install the extension-developer addon from https://addons.mozilla.org/en-us/firefox/addon/extension-developer/
+ 2) Open about:config, and ensure that "intl.accept_languages" does not have a user value (it will have "default" in the status column and be set to a list of language codes, such as "en-gb, en").
+ 
+ To test:
+ 1) Open a JS shell (Tools -> Extension Developer -> Javascript Shell).
+ 2) In the shell, click on the "enumerateWindows()" link
+ 3) In the list of windows, click on "chrome://browser/content/browser.xul". This puts us in main window context
+ 4) Enter the following:
+ 
+ string=Cc["@mozilla.org/supports-string;1"].createInstance(Ci.nsISupportsString);
+ string.data="chrome://global/locale/intl.properties";
+ gPrefService.setComplexValue("intl.accept_languages", Ci.nsISupportsString, string);
+ 
+ 5) Check "intl.accept_languages" again in about:config
+ 
+ Expected result:
+ - With Firefox 4.0.1+build1+nobinonly-0ubuntu0.11.04.1, intl.accept_languages will contain the value "chrome://global/locale/intl.properties", and the status column will say "user set"
+ - With Firefox 4.0.1+build1+nobinonly-0ubuntu0.11.04.2, intl.accept_languages should remain unchanged, and still display the default setting for your locale
