hi, yes the server component of screenshots is getting retired: https://blog.mozilla.org/futurereleases/2019/01/24/clarifying-the-future-of-firefox-screenshots/

-( That's a pity, the Save option was so convenient compared to having to dowload the screenshot.

Great so all my screenshots embedded in forums are going to disappear? Another mutilation of internet forum posts. How about an option to connect third party image hosting to the screen shots interface? (Since obviously the problem is hosting which costs money even though you are afraid to say so). Also I would have liked a where has the favorite button gone message with a link to the blog post, instead of just removing it and leaving me into the dark as to where it has gone.
