Hi there, adding to the discussion a little late, but grateful for your comments on this one. We at the small Munich-based start-up cliqz are heading in a kind of similar direction - please have a look at https://addons.mozilla.org/de/firefox/addon/cliqz-beta/ German-heavy at the moment, but going international soon, hopefully by the end of August. Please let me know your thoughts - we would be happy to take your suggestions and together with you make it more "amazing"! Thank you! Richard (richard@cliqz.com)
