How can I disable Developer Tools?

more options

Hi there,

When using Firefox, the developer tools box is constantly flashing up on the screen and disrupting my sessions

Shown here -> http://i.imgur.com/qqxmo89.png

Can someone please let me know how to permanently disable it? I have tried addons like Keyconfig, but they don't seem to be able to stop it from popping up every five minutes.

You are using an old version of Firefox (32.0), current version is 40.0.2. Updating often fix a lot of issues and improves safety.

Just update Firefox by following instructions here or download the last version from this link: getfirefox.com.

Sorry no, this isn't relevant to my question in any way shape or form.

You can try to toggle devtools.inspector.enabled to false on the about:config page.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Hi Co-rel

Sadly, no luck. I've tried disabling a few of the devtools values in about:config including that one to see if it might turn it off, but no such luck.

Part of me wonders if there's simply a way of disabling the hotkey (CTRL + SHIFT + C) since that would fix it. I think the issue is that my keyboard has a funny shift key, so occsaionally when I hit CTRL + C it's picking up all three.

You can consider to use Ctrl+Insert instead of Ctrl+C to copy text

  • Copy: Ctrl+C or Ctrl+Insert (Mac: Command + C)
  • Paste: Ctrl+V or Shift+Insert (Mac: Command + V)
  • Cut: Ctrl+X or Shift+Delete (Mac: Command + X)

You can also try to assign some code that doesn't have affect or "cmd_copy" to the Ctrl+Shift+C shortcut.

Sadly, as mentioned in the title, I've already tried using Keyconfig but no luck unfortunately. It just ends up copying (and) opening the inspector tools. Surely the devs included a way to turn this thing off?
