My Firefox version is 29.0, tagged as "Mozilla Firefox for Ubuntu / canonical - 1.0" Some web sites change their default language according to the HTTP request field named "Accept-Language". I expect those web sites to offer me a web page in French, however I always get the English version when browsing with Firefox. After some investigation, I discovered that my version of Firefox does not send an expected value for "Accept-Language". - Expected value: fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3 - Value sent instead: en-US,en;q=0.5 Tests with other browsers: - French Chromimum on French Ubuntu 14.04: the value is correct - French Firefox on French Windows 7: the value is correct. - French Chrome on French Windows 7: the value is correct. Maybe the problem is present with other languages. I don't know if it is related, but: - in Firefox's about:config, the value of intl.accept_languages is: fr, fr-fr, en-us, en - in a terminal, the "locale" command shows only fr_FR To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1322333/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
