Yeah, this is a legit concern.

Screenshots is implemented as a WebExtension. Unfortunately, the WebExtensions framework in Firefox currently appends items to the bottom of the context menu--so you'll notice this with other WebExtensions, too.

There's a bug open to change this behavior: http://bugzil.la/1325758 . If you'd like to hack on some browser JS, I'd be happy to help get you connected with a bug mentor on the addons team :-)

Thanks for your informative response! That's a very interesting discussion, and I'm glad to see support for at least moving Inspect Element back to the bottom in the short term.

Some of the use cases for precise placement capabilities seem pretty compelling, but here's hoping for accessible user customization options as a long term solution, perhaps in conjunction with the ability for WebExtension developers to set appropriate default placement, as long as that placement is not below Inspect Element. Inspect Element at the bottom is sacred!
