We lose a few hundred ms of perceived user performance by waiting for a click event when selecting a toolbox tab.

As a reference, browser tabs are switching on mousedown (in Firefox, in Chrome they are switching on click). Chrome devtools tabs are also switching on mousedown.

The code driving this is at http://searchfox.org/mozilla-central/rev/51eae084534f522a502e4b808484cde8591cb502/devtools/client/framework/components/toolbox-tab.js#56
