Firefox 42 will not allow unsigned extensions

I wonder if this will mean that all the extension version numbers will stop ending in -signed. I'm used to having any build number with -label in its name denote it's a pre-release and isn't stable [0].

I was recently searching for user agent switcher add-ons as part of a blog post [1] and almost all have -signed in the name. To some people it could look like the un-signed ones are more stable and better.

The -signed label was a one time effect to update existing extensions to signed versions (since AMO didn't want to arbitrarily bump the version numbers of all its hosted extensions). Future updates do not have this label.
