When I double click an AppImage, I get ab error ('Could Not Display "Something.AppImage"\n There is no app installed for "AppImage application bundle" files. Do you want to search for an app to open this file?'). That's in Nautilus. If I click on the file from the Firefox download thingy, it asks me how I want to open "file links" with no suggestions for what to do next. Thunar asks me to pick a program to open "AppImage application bundle" files with, but has no recommended application.

Dolphin does seem to support AppImages natively and will execute the file (after clicking through two security prompts). I guess KDE users are AppImage's target audience, then?
