File:Firejailed firefox xterm nautilus.png

Summary
Screenshot showing Firefox 52.4.0 (with two windows open) running inside an X11 sandbox (Xephyr + firejail, with Openbox window manager). An Xterm and Nautilus window are also open in the sandbox, showing the user's home directory. The main ("parent") desktop is running GNOME 3.22.2. Uploaded for use in a forthcoming mini-guide on X11 sandboxing (an addendum to Sakaki's EFI Install Guide).
