There are some pages that Safari won't open... just hangs. Here are the details:
1. 2 sites affected - https://www.airbnb.ca/ - https://tools.usps.com/go/TrackConfirmAction!input.action
2. Effects both 2012 MacBook Pro Retina and 2009 Mac Pro both completely updated
3. Opens fine with Chrome
4. Reset the browser settings and no extensions in use other than 1 password
5. They open fine in iPad Safari
6. Reset pram
Appears to be a Safari issue obviously.
Okay, after being out tonight I came home and tried the links for kicks again... they all work now. Furthermore I tried the link in this guy's thread who was having the same issues as me as well. It didn't work earlier for me but it works now. https://discussions.apple.com/thread/4579132?tstart=0
I didn't touch anything, change anything at all but let a few hours lapse. In the past day I vaguely remember OSX asking me for some kind of permission for facebook integration. I'm guessing that this somehow, and not locally, was messing up some HTTPS connectivity... timing out on something it was looking for but not getting.
