Familiar face

I desperately want Firefox to have a native RSS reader that can sync across multiple devices, and the homepage is an excellent place to implement that. (See: https://connect.mozilla.org/t5/ideas/revive-livemarks-rss-subscriptions-for-modern-browser-syncing/i...).

As for the other suggestions....

Wallpapers are nice, and are already an option on Android (albeit most of them are sponsored ads for Turning Red, and the appeal of Turning Red apparently is not universal).

Widgets for a Calendar or a clock might be nice, albeit redundant since most computer OSs have both.

Weather might be nice, but there do exist extensions that offer that functionality as well.

and the Privacy Stats? Eh..... sure, but I kinda appreciate that Firefox doesn't boast about how much it "blocks" the same way Brave does.

I like the Homepage as is. In fact, I disable a lot of the stuff on it like Pocket and typically keep just the search bar. But I'm not against better options for customization.
