Today I received a "one liner" reply from Dlink Support (as linked on the mydlink.com website. In short, it said they are not interested in this (above) problem with their website. Please note that I was not asking for support for my dcs932 (it works just fine), but rather that they fix their website so that it works with Ubuntu Firefox.
I suppose I should have expected this sort of thing from dlink. They did much the same with a router I had purchaced. I called support wrt a bug, and waited for them to fix it. When an update came out and the same bug still existed, I called again with the fix for the bug. Another update came out with; guess what: no fix. I called a third time, and they said that since (then) that the router was not longer supported, they were not interested.
I will say this: dlink makes reasonably good hardware, but in my opinion their software (hence their software writers) leave a whole lot to be desired.
Oh well, twice burned should have me learning my lessons well. No more dlink for me.
