Describe the bug
I'm unable to run AppImage binaries with firejail. The error is below:

***reading default rules**
Parent pid 18618, child pid 18619
Child process initialized in 12.24 ms
fusermount: mount failed: Operation not permitted

Cannot mount AppImage, please check your FUSE setup.
You might still be able to extract the contents of this AppImage 
if you run it with the --appimage-extract option. 
See https://github.com/AppImage/AppImageKit/wiki/FUSE 
for more information
open dir error: No such file or directory

Parent is shutting down, bye...

To Reproduce

Just run any AppImage with the default profile.

Additional context

We can fix this by not using the below line in the profile of AppImages:

protocol unix,inet,inet6
