How can I disable the Ctrl+Shift+M Response Design Mode feature in about:config?

I don't need it and I use that shortcut for something else. Even though my Ctrl+Shift+M shortcut isn't supposed to be "passthrough", it does still toggle the Response Design Mode on occasion. I'd like to disable the Response Design Mode entirely, and I'm guessing that I might be able to do that in about:config. I'm just not sure what to edit in there.

You can only disable access to all developer tools.

You can set this pref to true on the about:config page

  • devtools.policy.disabled = true

Close and restart Firefox to apply the change.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
