Hello,

I am trying to lock down Firefox 57+ for people to use at my company. So far I have a kiosk mode running with the only outstanding issue is by pressing F12 or CTRL+SHIFT+C the developer tools can be accessed.

I need to disable this but unfortunately the user_pref snippets I have seen posted about dont work (pasted below). Does anyone have any guidance on how this can be achieved ideally without any extensions.

user_pref("devtools.debugger.enabled", false); user_pref("devtools.errorconsole.enabled", false); user_pref("devtools.inspector.enabled", false); user_pref("devtools.layoutview.enabled", false); user_pref("devtools.responsiveUI.enabled", false); user_pref("devtools.ruleview.enabled", false); user_pref("devtools.scratchpad.enabled", false); user_pref("devtools.styleeditor.enabled", false); user_pref("devtools.tilt.enabled(3D View)", false); user_pref("devtools.toolbar.enabled", false);

Thank you!

On further review, is it possible to blanket disable all Firefox shortcuts?

See if one of these extensions can do what you want.

Note that the devtools.*enabled prefs are merely about what to show on the toolbar in the developer tools and not about disabling keyboard shortcuts.
