I went all in with 57 (the first 'Quantum' release) after having been a Chrome user for quite a while. I really haven't missed Chrome at all since I made the move, and in fact, am continually impressed by the little things in Firefox that I keep discovering. Not to mention the speed.

These changes look like they will eventually make things better, especially for extension developers and those of us who get to reap their benefits.

Keep up the good work, Mozilla.
