EDIT: we are seeing a higher rate of expected failures on Firefox and are trying to run this down now. We think it might have something to do with other add-ons, specifically add-ons that might be changing cookies expiration times. Also, please tell me if you have Content Blocking set higher than Standard in about:preferences#privacy.
Very sorry to hear this. When you save from Chrome, are you using the current Save button, version 4.0.79? Are you running any other Firefox add-ons, anything that might be clearing your private data?
