Comment:

 I believe there is a conflict between what Torbutton does and what is
 already included in Firefox. When I first denied to spoof the locale
 (twice), but later clicked on the corresponding box in the "General" part
 of about:preferences to set it to "on" ("spoof locale"), in this session
 the "accepted languages" seem to be changed to only include en-us/en. But
 after closing and restarting Tor Browser my locale (de) is included again,
 although the checkbox setting is not changed. I first noticed this when
 visiting trac.torproject.org. What is even more weird: When I uncheck the
 box to delete "German [de]", after a restart it is there again,
 independent of the setting of the checkbox.
