I have looked at https://developer.mozilla.org/en- US/docs/Installing_extensions and I believe the xpi file is in the wrong location. After running:
sudo ln -s /usr/lib/thunderbird-addons/extensions /usr/lib/mozilla/extensions/\{3550f703-e582-4d05-9a08-453d09bdfdc6\} (where {3550f703-e582-4d05-9a08-453d09bdfdc6\} is the ID of the Thunderbird application) the UI is now in Norwegian. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1093678 Title: UI appears in English, not in configured language Status in “thunderbird” package in Ubuntu: New Bug description: $ dpkg -l thunderbird* | grep ^ii ii thunderbird 17.0+build2-0ubuntu0.10.04.1 Email, RSS and newsgroup client with integrated spam filter ii thunderbird-locale-nb 1:17.0+build2-0ubuntu0.10.04.1 Bokmål, Norwegian; Norwegian Bokmål language pack for Thu ii thunderbird-locale-nb-no 1:17.0+build2-0ubuntu0.10.04.1 Transitional Norwegian language pack for Thunderbird I have selected "Norwegian" and "Norwegian Bokmål" as sole languages in System - Administration - Language support (this will install thunderbird-locale-nb-no although it is only a transitional package). Nevertheless, Thunderbird displays all menus in English. Tested with a fresh user profile. This issue seems to be experienced by many other users here: http://ubuntuforums.org/showthread.php?t=1973240 It appears that thunderbird-locale-nb mainly contains the unpacked xpi file /usr/lib/thunderbird-addons/extensions/langpack-nb...@thunderbird.mozilla.org.xpi For comparison, the "thunderbird" package has dumped a /usr/lib /thunderbird- addons/extensions/\{972ce4c6-7e08-4474-a285-3208198ce6fd\}/ folder in the same extensions folder.
