I am using nightly regularly but since firefox changed their
about:home to the animated page I've taken fond to it and want to use that page on nightly.
I suppose I can just change the home page but what do I change it to?
On about:home, press ctrl+U (this shows you the source of the page). Then look at the title bar. In order to get the xhtml file, you would need to extract the .ja file. This page is of help: https://developer.mozilla.org/en-US/docs/Mozilla/About_omni.ja_%28formerly_omni.jar%29
