Whether or not it works in GM 0.3 doesn't really matter; what matters
is whether or not it works in FF 1.0.3 - that whole bunch of noise
about extensions possibly breaking, and security, and not letting
content touch chrome's DOM view, and people needing to go back and
rewrite extensions that will run in pre-1.0.3 to use XPCNativeWrapper?
That was aimed right straight at your disabler (whether or not they
knew it was).

Web sites may always be able to disable a script by morphing their DOM
to duck an XPath expression, but if content can actually prevent
chrome from accessing something, then it's a Firefox bug.
