How remove the "Firefox Developer Tools" from Firefox 28.0? Is there a way or script or option in about:config to remove them permanently?

Answer 1

You can't remove them, because they are integrated into Firefox. Though various tools have a corresponding preference in about:config to enable/disable them.

Just search for devtools.*.enabled there and set all of the appearing options to false.

See also the thread about this in the support.mozilla.org forum.

Note: As long as the DevTools are not opened they don't use any memory.

Answer 2

The above doesn't work on Linux. Inspectors and all still popup.

[edit]. There isn't a way to disable this inspector, but with this extension you can disable shortcuts: Keybinder: https://addons.mozilla.org/en-us/firefox/addon/keybinder/
(Above is to replace Customizable Shortcuts by Tim Taubert, which is no longer developed/removed)

Config -> Shortcut mapping -> change > (find shortcut, disable).
