Hm, so if I develop on this I will still have to test in the regular stable Firefox release, that seems unfortunate.
Having more tools in a developer edition compared to the regular version of the browser seems fine, but at least for me I would like run it with the same rendering engine my users are likely to run.
I don't understand the problem. Responsible web developers test across multiple browsers anyway, and this edition allows you to hook the developer edition tools into other browsers.
