Disable devtools inspector in 63.0.1
Firefox was updated to 63.0.1. Now, the volume keys (F10, F11, F12) on my Mac (10.11.6) no longer work in any program. In firefox, they are shortcuts to pull up the web developer three pane inspector. I want to turn off/disable the inspector/debugger/devtools/ whatever is responsible for this window that I will never use. I could not disable this function in preferences or change the function of the F10-12 keys. I tried turning off the tool in about:config. Searched "devtools.*.enabled", "devtools.inspector", "debugger.*.enabled" and changed "true" values to "false". F10 and F11 are no longer shortcut keys but F12 brings up the pane (in my ass). How do I turn off these devtools so I can use the volume keys in Firefox and other programs?

Try to set this pref to true on the about:config page.
- devtools.policy.disabled = true
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.
Note that this disables the developer tools completely including the Tools menu, so you won't be able to use the developer tools for troubleshooting if required.
You need to close (Quit) and restart Firefox to make changes to this pref effective.
