Problem: washingtonpost loads one ad image from images2.laih.com. That 
hostname is served by a buggy, invalid, broken DNS server.

$ time host images2.laih.com
images2.laih.com is an alias for p.mii.instacontent.net.
p.mii.instacontent.net has address 65.216.116.114

real    0m0.026s
user    0m0.004s
sys     0m0.003s
$ time host -t aaaa images2.laih.com
;; connection timed out; no servers could be reached

real    0m10.009s
user    0m0.003s
sys     0m0.004s

See the difference? They drop AAAA queries. It's invalid, broken and buggy 
behaviour.

Mozilla people were considering adding those known domains to a killfile. 
We were too, but we never got around to implementing it. I don't know if 
they have.

We would simply discard any and every query to those known, broken domains 
until they fixed their DNS servers. The plus side is you would not see 
their ads in your pages.

Note: there are other big sites that would be included in that list.
