Also don't work:
devtools.inspector.enabled = false

This is currently expected, as some tools are considered "core" tools that are deeply integrated with each other.  This is why the Toolbox Options pane (gear icon) doesn't have checkboxes for these tools.

In any case, we can use this bug to discuss if that still makes sense.

We are using a modified kiosk-mode Firefox for testing kids (or their teachers ;-) in school and would like to disable any distraction from the tests. (distraction, not cheating, we know that there is a plethora of ways to cheat). If disabling should not be possible, removing these options would be great!
(and possibly a way to remove the develop bar from the UI?)

Does this mean you are build Firefox from a source tree?  Or just customizing with prefs and add-ons?

Until now, we tried to archive our target without building and just customizing

Are you wanting to disable the Developer Tools entirely?  Or specifically trying to hide the Inspector and Debugger panels from the Developer Tools toolbox?

Write a style to userChrome.css may be able to as workaround for now.

Filter on TEAPOT-SPLINES.

More information needed from the reporter about what exactly they need.

We would like to have a way to configure the browser so that all devtools can be disabled. We tried to archive that by disabling every single component which didn't work hence the bug report.
Wie fixed the problem by hiding the components using the userChrome.css style sheet.
