I'm running the latest beta (0.8.5) Chrome extension on Linux, and I've been having excellent luck with it so far (thanks, everyone!). Just tried to login to our corporate ADFS instance (hosted by Microsoft as part of Office 365) and it won't fill the login form.
Obviously, this isn't enough information; please let me know what else I can do to assist and I'll do so...
