If you find that the animation stops every time you close or open a new window.

Here is the solution:

1. Open a new tab, and type "about:config" at the URL bar, then search for "lightweightthemes" with the filter.

2. Change the values of "lightweightThemes.persisted.footerURL" and "lightweightThemes.persisted.headerURL" from true to false( by double click on them).

3. After doing so, restart Firefox and you will see it works! You don't have to install any add-on.
