Besides that, the browser is supporting Quicktime, Java and Flash content (as long as the required Flash plugin is installed on the system). In the browser window there is no right mouse (or ctrl-) click popup window available, links requesting to be opened in a separate window can be set to be blocked generally, to open in the same browser window or in a new SEB window. It can also be set whether users can quit SEB and if it is required to enter a quit password to do so. Display and system idle sleep is also prevented while SEB is running.
SEB disables the macOS Dock, the process switcher (cmd+Tab/cmd+Shift+Tab), menu bar, the Force Quit window (cmd+opt+esc), normal reboot (ctrl+cmd+eject), normal shutdown (ctrl+opt+cmd+eject), hiding the application, printing and Exposé.
