So Mozilla already offered us Cloud account to sync our settings, bookmark, and other things. Then why not sync our notes, containers and screenshots and why not offer the ability to save screenshots in the cloud? Where we can share both notes and screenshots using public URLs.
Many would pay for the file hosting. Offer 5 gb free for Screenshots & notes saving in the cloud and then ask for payment for more file space.
I think it's a WIN- WIN for everyone!
