Nit: I think you mean "...for canceling the downloads and closing the
browser..." (2 places here, 2 places in google_chrome_strings.grd)

These more verbose strings are descriptive, but I'm not sure whether we want/can
have something this long here.  I'm a bit uncomfortable with changing the text
of the existing string significantly unless you're working with the UI leads
and/or tech writers; otherwise can you leave things close to how they were?

Sorry, and will do.
It's not surprising that that panel isn't laid out correctly on
Windows/Linux/whatever that screenshot's from. That's why I was saying I'm happy
for the new titles to only appear on the Mac, because the Appkit will do the
right thing.

A good catch. I was worried about it and meant to do something. Then, I forgot
that. Anyway, http://crbug.com/455005#c7 (which was seconded by leer : UX
designer). 

I'll ask him to review the strings after updating the CL.
