Haha yes that was trying to figure out your x64 problems with FF, not sure if you tried my suggestions.
Anyways here is a link to the jump list feature (bottom of the page)
Seamless with Windows 7 - Microsoft Windows
I will say not everyone will use it, but I use it all the time now because the websites I frequent have integrated it very well. You can think of it as creating glorified shortcuts for different websites. I have bing.com pinned on the bottom and it is a good example if you right click the icon you can go directly to weather, travel, news, etc. without having to open the browser than navigate to it. But its worth checking out! :thumbsup:
