Firefox Android Add-on Development & UI Options

I know ui/button isn’t supported on Firefox Android, and also looks like it won’t be supported anytime soon since WebExtensions is the priority right now.

However, when I was reading about this a month ago, I read somewhere that it is possible to create an add-on section (just like top sites, bookmarks, reading lists) on the home page.

I have been trying to find that article since a long now, but can’t.

Can it really be done?

Thanks!

I think you’re looking for Home.jsm -
