To be clear, the issue is that thumbnails don't have ABP enabled, not
that ABP falls over in general.

It's a trade-off, right?  You can have thumbnails with ABP that jank
the browser, or you can have thumbnails without ABP that don't.  (AIUI
the oop business also fixes the issue where thumbnails showed private
data, like bank account info.  There are probably other things it
fixes too.)

Showing banner ads in the screencaps doesn't seem like a big deal to
me compared to what we get in return...  I guess the biggest issue
from my perspective might be that we're allowing advertisers to track
us, by making HTTP requests we otherwise wouldn't.  Hopefully we send
the cookies to /dev/null, but even still they get our IP.
