Steps to reproduce:
Updated to version 13.0
Just the beginning, but "more..." links under Google News categories won't work, article links do work. Citrix Receiver Webacess plugin v13.1 was working before upgrade, now won't load, blank screen.
Google News -> WFM.
For the Citrix Stuff you should probably file a Report there.
