The code works fine with xulrunner 1.9.0.x. By the way, autocomplete works with no problem. Reproducible: Always
XULRunner has been removed from the Mozilla tree: see https://groups.google.com/forum/#!topic/mozilla.dev.platform/_rFMunG2Bgw for context. I am closing all the bugs currently in the XULRunner bugzilla component, in preparation for moving this component to the graveyard. If this bug is still valid in a XULRunner-less world, it will need to be moved to a different bugzilla component to be reopened.
