That's not the plan.

We've identified that XUL is a growing impediment to Firefox's continued success. Exactly what that means (there are dozens of reasons and dozens of ways forward), and how we're going to tackle it, is a big topic that we're digging into.

Yes, removing XUL implies that XUL-based add-ons are not going to last forever. That doesn't mean there won't be a path from here to there: everyone involved recognizes that add-ons are important, and we're increasingly going to be shipping parts of Firefox itself using add-on mechanisms.

And I haven't seen anyone seriously consider killing Gecko: it continues to be awesome, and one of the motivations for deXULification is to allow our platform developers the freedom to only focus on supporting HTML UIs, not a mix of HTML and XUL.
