Yea i think it's broken a few things in 5.5 as well, I may have to fine a downrev version of FF prior to 30. It's broken the upload function for sure, but wasn't sure if it was officially unsupported or not. We will probably have to advertise supported browser revs in our deployment going forward.
As a point of curiosity though, did the CIP replace the VMRC of the 1.5 days?
