Some time ago I found that I couldn't access my Bank and Credit card web sites via Safari and as a result, I contacted the Bank & Card companies to ask for help. Using Firefox was a short term answer S it didn't seem to suffer from whatever was causing this. It for fixed and things were ok again but, as we now have Mavericks & a new version of Safari plus an updated version of 1Password, the problem has reappeared. Again, Firefox works just fine but not Safari. What I see now is a warning saying something about 'null notices' but I've no idea what that is. I've sent an email to 1Password to see what they say but I know they are very busy just now. Has anyone else seen this or experiences a similar problem? Have you found a fix?
