I compile a unbranded version of Firefox for each released version on my private repository for AUR packages, automated and without the need of intervention at all.

I'm currently running the branded release but I could pick unbranded, beta, dev or nightly editions of Firefox if I wanted. It's not hard to automate and especially with the unbranded version you have permission to distribute the binary that results, a permission you don't have with the branded edition.

You can also use the Nightly or Developer Edition of Firefox as well.

Yes, you could. What about the person Mozilla claims to want to get into coding? They have to choose between getting the regular updates vs being able to tweak their addons.

And do you plan to set that all up in the middle of your workday when a forced update disables your extensions?

Again, you can also use the developer edition, which also allows unsigned addons and has automatic updates but also doesn't disable your extension. It's specifically meant for people getting into coding.

Plus, there is more ways than developing FF addons to get into coding that Mozilla wants to stimulate, developing the browser itself or websites is also an alternate goal you can join in addition to trying out making your own addons.
