Did some updates for Yosemite today: Security 2016-002, Safari 9.1, Remote Desktop Client 3.8.5 and iTunes 12.3.3. Safari is now unusable. Constant errors trying to load websites, sites try continuously to reload and Safari Web Content keeps quitting. Tried to delete Safari and restore from TM, but, OS X won't let me Trash Safari. I tried going into TM manually and dragging the older version of Safari out. That worked, but opening that older Safari still gave the same problem. It works fine from another Account, so there's obviously something in my Account causing the problem. Any suggestions as to what is wrong?
