About this Add-on
Since version 0.0.5, it does not require DOM Inspector, if you have
not installed DOM Inspector it will attempt to use Firebug or
Firefox's own Inspector to position an element.
Usage: When you need to inspect elements, doing "Shift + secondary
click" on them will automatically launch the DOM Inspector (or
equivalent) and navigate to the element.
