Pretty much yeah. And some ad-blocking + anti-tracking features,
provided by the same plugin.

I can do that no problem. I shall update this in the pkgsrc-wip repository.

You are right it is aggregation.

You are welcome. :)

I do not think they serve "Ads" yet, but it is something that might
happen in the future. What I meant is the "search results" are
presented from their end when you start typing in into your address
bar as of now no "ads" are being served (Last I checked).
Based on the above description I have made some minor corrections and
made this for the DESCR.
"Cliqz develops novel Internet browsers that incorporate proprietary
features such as search and anti-tracking. Cliqz desktop browser is
based on Mozilla Firefox.
Cliqz pre-installs the Cliqz add-on, which causes search terms to
be sent to Cliqz as the default search engine. In addition the
HTTPS Everywhere addon is installed, and an addon to manage consent
to data processing."
Let me know your thoughts on this.
