Ever since I upgraded to mavericks, Safari has become a nightmare to use. I was trying to check in online for a flight and when it came time to print out the boarding pass, it would neither show it or print it. It refuses to open up any pdf file and says something about not being a secure certificate or says that I must start acrobat reader and accept the user terms first, but there is no way to do that. Acrobat reader works fine in firefox, so what is all of this new security crap going on with mavericks and safari? And how do you get rid of it? I am ready to dump this crap browser and just adopt firefox.
