Automatic Firefox submission

[astral-sa]

For submission, web-ext has a sign command that can work, albeit with this warning:

Setting --channel=listed for a new version of a listed extension is not well supported. It uploads your new version to addons.mozilla.org as if you’d submitted it manually. However, the command will fail and you’ll have to check addons.mozilla.org/developers/addons for the correct status.

From what I understand about it from some searching I did the other day, it can be worked around by ignoring the exit code (though you still don't properly know if it worked/what that status is without checking manually). It's not quite ideal

We'll also probably want to set strict_min_version in the manifest since the default versions a.m.o fills in when submitting an extension are a bit off.

Another option for signing is using https://github.com/mozilla/sign-addon/ directly instead of via web-ext.

Oh, and as a side-note, if you don't already have 2FA set up for your Firefox/a.m.o account, it'll soon be a requirement: https://blog.mozilla.org/addons/2019/12/09/secure-your-addons-mozilla-org-account-with-two-factor-authentication/

Something that is slowing this down is I still have some slightly-different default settings defined for Firefox. Part of the storage.local migration will make default settings easier to deal with (not having to specify them in two different locations, for example).
