^ I support the decision to simplify and modernize the architecture in Firefox, even if it does disrupt extensions. Someone wrote this below, and I think it addresses your post perfectly: "I welcome a replacement for XUL.

"Maybe Mozilla can't pull that off, but I would certainly like to see them try."
