Two things I've found so far. You can install Google Chrome as an alternate browser. It's good, but I'm not sure yet which browser is best for the KFHD.
Splashtop Desktop Streamer is a little twitchier on the KFHD. I used it once to test it, then when I went to reconnect it would see my desktop but fail to connect. After lots of unhelpful googling, and fiddling with the settings, I was able to reconnect by rebooting both the Desktop and KFHD.
