I think it's safe to say that many if not most popular extensions will be provided API support and converted over. I think the real issue is that innovation in the extension space is effectively over - the Firefox extension system is so vibrant because anything was possible. Now Mozilla is reducing the possibility space to that which is provided by the much more limited WebExtensions and adding in support for existing popular extensions. But new extensions, doing things yet undreamed of, will no longer be possible. I'm not sure what the distinguishing features of Firefox will be moving into the future. More and more, I think it's becoming Just Another Browser, with a better ideology behind it. Well, that's not a winning formula. I'm really disappointed and I don't know what to do other than stay on old versions of Firefox as long as I can.
