nytimes pages that fail in iceweasel

[Steve Kleene <skdeb@syrano.acb.uc.edu>]

A lot of sites on nytimes.com don't work correctly in my iceweasel, e.g.

http://www.nytimes.com/interactive/2016/us/elections/fact-check.html#/factcheck-109

If I click on any of the many "Read more" links, I get nothing.  I don't
guess this is flash.  Lots of flash sites work for me, and they ask if I want
to allow flash.  The nytimes pages do not.  Other examples:

http://www.nytimes.com/interactive/2016/01/02/opinion/collins-our-new-year-quiz.html

I am running iceweasel 38.6.1 under Wheezy.  Any ideas what format these pages
use or why they are failing?

Thanks.
