I think this should remain a button (here and in google_chrome_strings).

[Dan Beam, 2014/10/23 03:05:43]

note: this is already a link in appearance

Right, but it could stay as a button-that-looks-like-a-link. In the world where
we ran around adding role=link to things instead of this (better) solution, I
think we'd want to leave role=link off this one.

However, that can be a discussion for another day.

           Chromium updates automatically so you always have the freshest version. When this download completes, Chromium will restart and you'll be on your way.
