About an hour ago, both Chrome and FireFox no longer accept master password. Nothing happens. Password typed manually and also via Yubi-Key channel #2. Go to LP.com and the LP website allows signin using master password without a glitch.
Un installed and reinstalled LP plugins for both browsers without any change in non-functionality. Restarted computer, no change.
I am getting the same issue with the Firefox addon today. Tried a new firefox profile, different versions of lastpass. Tried removing Firefox and deleteing all the %appdata% stuff. No joy. I've even rolled back using system restore but nothing works! I've been a Premium customer for 5 years now and this is really making me consider moving away.
