We already had a TODO item about this[0] in the todo/discuss state.
Thanks for the heads up!

T(A)ILS shall not rely on such good-willing promises
=> T(A)ILS shall protect users from DuckDuckGo as much as from
Scroogle or anyone else.

Scroogle also has a SSL version, which is used in T(A)ILS.

Scroogle has no JS or non-Lite versions :)

What would be the advantage in T(A)ILS?

This hides to the clicked websites:

  - the fact the user is coming from DuckDuckGo
  - the search that was performed, in case GET is used -> see the
    second "privacy" setting


On the other hand, I wonder how this is implemented without telling
DuckDuckGo what site the user is going to visit... which would be
pretty bad privacy-wise.

I fail to understand the privacy enhancement this brings. Could
someone explain? I can clearly see the privacy downside in case
referrers are not disabled.

This would be a great thing to have.

According to the settings page I just visited the HTTPS setting is Off
by default.

Worried about how the default settings could be changed, I have had a
quick look to their website and it seems this can be done using [URL
parameters](https://duckduckgo.com/params.html) rather than cookies,
which is probably desirable in T(A)ILS context. We should be careful
about this though: using a non-default set of URL parameters would
help DuckDuckGo fingerprint T(A)ILS users.

Bye,
