When I installed Safari 12 it came up with a message that the Download Videos and the Screenshot Page extensions weren't safe and had been removed. The Download Video app still works (by dragging in the web address) but the Screenshot Page app (which allows taking screenshots of long webpages) no longer works at all.
I reported it in this ticket: 276030022
The Safari 12 message only appears the first time you open Safari (and only if the extensions were loaded in Safari 11).
