washingtonpost.com refreshes on resize.  This should not happen.

http://bugzilla.mozilla.org/show_bug.cgi?id=235871#c11 might be an explanation
for this, though I can't tell for certain from the page source.  Quoting the
comment:
<i>

As far as I can tell, the cause is as follows:

1)  Websites detect a 'Netscape' browser

2)  Erroneously expecting old NS 4.x behavior, the site reloads
    the page on resize using javascript onResize
</I>

See also bug 121716 for an older problem with refresh on page load that listed
washingtonpost.com as an example URL (though this does not seem to be the same
problem).

The offending code is:

if(!window.saveInnerWidth) {
  window.onresize = resize;
  window.saveInnerWidth = window.innerWidth;
  window.saveInnerHeight = window.innerHeight;
}

function resize() {
    if (saveInnerWidth < window.innerWidth ||
        saveInnerWidth > window.innerWidth ||
        saveInnerHeight > window.innerHeight ||
        saveInnerHeight < window.innerHeight )
    {
        window.history.go(0);
    }
}

which is located in:
http://media.washingtonpost.com/wp-srv/homepagessi/_browser.js

This code does not affect IE because IE does not implement the innerWidth and innerHeight properties. 
The solution to this problem is to check for Netscape 4.x before installing the onresize handler.

we introduced a hack a while back that should prevent these resize issues. It no
longer resizes.
