I am running Firefox 33.1 on Windows 7 Ultimate. In the recent past I get the "This Connection is Untrusted" message every single time I sign into a hotel or airlines club to get access to the internet. The accompanying "I Understand the Risks" option is not present, just the "Get Me Out of Here." If I did not have Opera and Chrome and IE on my computer as a back-up I would not be able to access the internet other than when I am at home. Please do not suggest clearing cache and cookies. In my 30 + years of computing experience the only time that has helped is with a password issue, when a password seems to get locked in.
