Convenient and useful tool, but it prevents me from using the element picker from FireFox DevTools, because this extension shares the same keyboard shortcut (Ctrl+Shift+C). I could appreciate if it were rebindable.

Nice add-on, but an important drawback for me: it overwrite the Devtools Inspector's keyboard shortcut (Ctrl + Shift + C) on Firefox.
I'm sorry not to use this extension as long as the problem persists.
