Notes by Firefox still supported?

Just started using Firefox.

I love Notes. It’s clearly missing a few simple features (such as the ability to check off items on a list), but I love the way it works.

It seems like Notes might have been left out to dry - a year since the last update. Does anyone know if there are any new features on the way? I would love to abandon Google Keep altogether, but not if this app won’t be supported soon.
