Just trying to run the latest version of ImageMagick which comes as AppImage:

@rusty-snake commented on GitHub (Nov 1, 2019):

It should work with

firejail --noprofile --appimage ./ImageMagick-a481ea5-clang-x86_64.AppImage identify index.png

Can you confirm?

@rusty-snake I can't see any difference in your command line as compared to mine - apart from the order of options? In any case, with your command line I get the same result unfortunately.

I found a work around: add --rmenv=APPIMAGE.

# symlink was used to invoke the AppImage

I can't see any difference in your command line as compared to mine - apart from the order of options?

--appimage should be the last firejail argumen.

   Start an AppImage program:

         firejail [OPTIONS] --appimage [appimage-file and arguments]

@rusty-snake Yeah, this solves the problem! Not sure if you want to close the ticket now, or improve on the firejail side but that's a working solution.
