X-Men Facebook Add-On Gives You An Alternate History Timeline

Okay, I'll say up front that I don't think this was working for me in the way it should but you might have more luck.

Fox have launched an X-Men tie-in Chrome plug in that mucks about with Facebook and gives you and Days of Future Past-ified timeline. In theory.

If you can get it to work, please take some screen captures and share them.
