'DOM' panel in FF DevTools unfortunately still doesn't distinguished between inbuilt native DOM nodes and custom DOM nodes from JS code - making the DOM panel still completely useless. Firebug grouped non-native DOM nodes (the interesting ones for devs) and sorted them on top, and marked them in bold font - non of these is in the new FF. Until DOM panel still a work-in-progress, I cannot switch.
I still keep a Firebug 48 with old Firebug addon around, because of the awesome DOM panel (that also Chrome doesn't have).
