Most websites I visit now cause the "A Problem occurred with this webpage so it was reloaded" to occur. And I get the "Safari Web Content quit unexpectedly." pop up window. I was barely able to get Macrumors.com to load and get this post started. I ran the update yesterday for Safari 9.1, iTunes 12.3.3, and Security update 2016-002. And then the problems began. Running Mavericks 10.9.5 No Problems with Chrome Browser.
