Safari itself is an ad-blocker, with its "reader mode". I could hardly imagine opening a newspaper page without it. Actually, my iPad 2 isn't powerful enough anymore to open a newspaper page, except if I use the reader mode.
Firefox as well. I use Pocket as a perferred reader generally, though its failure to provide a means of navigating directly to sites, or of showing a navbar, is annoying.
(Pocket ... has multiple annoyances. It's better than the alternatives, so far as I've tried, but that is one hellaciously low-set bar.)
