This email represents an intention to start investigating moving away from XUL/XBL. There are a number of areas to explore here like how to properly handle L10N, add-on overlays, and where to go native vs markup. At the same time we're actively moving over to e10s (electrolysis / per process tabs). There will be followup communication about who is doing the work and what work is being done but now is the time to add your concerns and comments or offer support.
