Firefox localization
====================

Example installation of a dutch (nl_NL) language pack. Note the use of various
versions of the locale's name: "nl" (name of the XPI file) versus "nl-NL"
(value of the config variable) versus "nl_NL" (the official ISO name).

* Install the "nl.xpi" language pack using this SlackBuild script. Create a
  Slackware package using the following command (use your firefox version and
  language):
    # VERSION=21.0 PKGLANG=nl ./mozilla-firefox-l10n.SlackBuild
* If the Slackware locale already is set to "nl_NL" in your profile script
  "/etc/profile.d/lang.sh", then you can use "about:config" to set the boolean
    intl.locale.matchOS = true
  which will force firefox to obey the locale setting of the OS. My package
  does this for you automatically.
* If your locale is not equal to the language you want to use for firefox,
  you must explicitly set the interface language. First make sure that
    intl.locale.matchOS = false
  or else your locale setting will always have preference, and then set:
    general.useragent.locale = nl-NL
    intl.locale.requested = nl-NL
    (the former for Firefox < 59 and the latter for Firefox >= 59).
  This will cause the firefox interface to show in dutch after a restart.
* Alternatively you can install this add-on to manage the language selection
  in the firefox menu:
    https://addons.mozilla.org/firefox/addon/locale-switcher/

Enjoy!
