Whereas DuckDuckGo is an eminently sensible name of course? It's just bloody quackers if you ask me.
Personally I use PaleMoon for browsing, with Startpage for searching.
I gave up on Firefox when they decided to put the page back/forward buttons IMMOVABLY over on the left of the page. Why would they do that? - Who knows - it seemed completely pointless, and designed only to annoy, but it chased me away anyway..
Just noticed the other day (on the page in small print) that Startpage also offer a (paid) one-click PGP email encryption service as well, though they don't seem to make much of a thing about it.
