Yes, Firefox will by default state its preferences for language and
character set. Torbutton hides these when enabled.

That sounds like a good idea. I've applied the change.

Right. This needs more investigation, but one option is to set a
cookie with the language setting, and then redirect to a different
page. Then the referring URL will not include the language choice. We
would set a cookie, but that would only contain the language, not a
user ID, and could be set with a very short expiry time.

OK, it's applied and I'll test it before the next release.
