What sorts of existing extensions will not be possible to port
Before you get to "what", you've first got to answer "who".
Who is going to port extensions.
There is a whole slew of extensions that are, that have been, that have not been looked at, that will not be looked at that will simply vanish.
Up till now, there has been little need for an extension author - that is one who has long stopped supporting their extension, an extension that just "is" - is there, should work, probably, you want to use it, go ahead - kind of thing, that was automatically (automagically) made "compatible" with later versions of FF (maxVersion), that may have automagically had a known function or two "fixed", no initiative taken by the author.
Going forward, its rewrite & that assumes that the needed functionality even exists.
And just
who is going to do it?
Certainly not the original author who has since put the extension into "drydock" - even if presently continues to work. Certainly not Mozilla - they won't give a rats ass.
In the end, no one will do it.
Maybe someone will step in, someone who is only out to monetize things.
Or backhandedly does so (even if they do happen to "disclose" such things on AMO).
