I got the new Firefox 12 and I hit the "Inspect Element (Q)". I'm used to hitting "Inspect" and getting FireBug, now I get the Firefox inspection tool. It looks nice, but how do I turn it off – not disable it, but stop inspecting the current page?
I have to close the tab, when working on a large web application, sign back in and re-setup everything I was testing to get back to a normal view. Big waste of time.
