I was liking this till I tried to watch a video. That site dropped a script on Firefox that had it push and keep it current. Using that page it was nice that it was always current. I went to a different site within the same browser and even though the WU page was no longer open I kept getting a hiccup in the video. Got watching the task manager and could see the spike in CPU usage. I had to completely close all the browsers to clear it.
