So is Thunderbird still using XUL or not?

  If yes it's only a matter of time until it transitions away from it too.

  Likely only because it doesn't see enough attention to be migrated.

  Yes and so is Firefox. So far they only removed XBL not XUL, and while they are slowly migrating things to HTML most of the UI is still XUL.
