Main blocker here is flash which does not work under Wayland.
Is Flash not working under anything really a blocking problem? Its set to be officially deprecated in 2020 and Adobe and many others have already pushed for removal of it.
I'm honestly curious. If there is something i'm not considering.
I don't want to regress any major functionality that X11 Firefox version provides, that will cause lot of confusion among users.
