Just running through the test scenarios, one of which is testing support for FF4. I've made the changes in the browser config as noted in the docs, restarted FF but I get the error "the addon could not be downloaded because of a connection failure on <zcmserver>". I clicked "Allow" immediately prior to this, but it's not had any effect.

Anyone else come across this one? Admin w/s is Windows 7 x64 SP1
