A word of warning to others: Not a good start. Trying replace my current installation of Firebug with this one caused my Aurora to enter a constant crash-loop.
Entering safe mode, uninstalling the existing version and attempting to close all tabs related to Firebug seemed to fix the problem.
So you may want to try removing your existing Firebug before installing.
