If you have any questions about add-on support in the new Firefox for Android experience, please post them here!
Are there at the moment any “official” ways for a normal addon developer to test their extension in that environment? Is this something that requires just"some special settings, a special build and/or some additional software that’s available to the general public, or does it require something that only developers specifically approached by Mozilla can have?
Not yet – the team is working on that now.
Just to set expectations, though, we’re still figuring out how broadly we will support extensions on the new Firefox for Android. We should have an update on that decision in a few weeks.
