I can toggle the developer console using the key Command-I on firefox, as you can see in the screenshot belowHow can I easily detach the developer console using keyboard shortcut from the browser? I want to avoid resizing the browser everytime just to make the icon 'show in seperate window' in the toolbar visible.
What is the keyboard shortcut to detach a developer console in Firefox?
firefox;mac
Once you undock it it stays undocked for that website. You could try firebug addon for firefox as an alternative. Does basically the same thing but might have the shortcut you're looking for.
