It's all open source right? You are not the first person I see complaining about losing XUL, why is no one forking it instead of just making sarcastic comments? I thought that was the whole point of open source, that when the original maintainer loses interest the community takes over. You even say in another comment that the effort is not very big (I don't know, never seen the code) so why not?

You have to build the entire pipeline again. I am not sure if Mozilla is even in the interest of keeping TB build infrastructure around.
