Ben Goodger's blog says, 'I have just rev'ed the app extensions version
to 1.0. This means that all Preview Release extensions will break. You
must update the maxVersion values in your install.rdf appropriately
when you update your extensions and themes. Please read this document
(http://www.mozilla.org/projects/firefox/extensions/updating-for-1.0.html)
for instructions how, and how to update your listing in
update.mozilla.org if you're listed there.'
