Well I agree that cleaning up overlay usage was overdue. Otherwise the simple post XUL world world is just dumb. Removing things without a functional replacement and putting in spaghetthi code seems to be the current mantra. Preprocessing with include files is even worse.

This is hopefully the last thing you’ll ever hear about XUL overlays as they have now been completely removed from Firefox[1]. For those unfamiliar with overlays, they provided a way to merge two XUL documents and were mainly used by legacy extensions and in several places within the Firefox UI. While overlays served a purpose, they were removed since we no longer support legacy extensions and they added unneeded complexity to Firefox.
