Hi,

The people who answer questions here, for the most part, are other Firefox users volunteering their time (like me), not Mozilla employees or Firefox developers.

If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

Hi Blaw, I don't think there is any way to create a new section on the built-in Firefox Home / New Tab page for an animation. There are add-ons to build your own page with a background image. As an example:

https://addons.mozilla.org/firefox/addon/new-tab-tools/

Or you could select an outside page as your home page. More info in this article: How to set the home page.
