How to set default homepage in safari 6? Since downloading mountain lion and safari 6 I have lost the ability to set my home page.  in safari preferences there is the ability to tell it what you want for a home page but it does not take.  instead I always get this:  http://d3.zedo.com/jsc/d3/ff2.html?n=790;c=3603;s=2952;d=16;w=1024;h=768.  I want to know how to get rid of this and get my preference working instead.
Two options come to mind:


Reset Safari (in Safari menu), restart the application and try again
Quit Safari, rename ~/Library/Safari to ~/Library/Safari.old and try again


If the second options work, quit Safari again and copy Bookmarks.plist from Safari.old to the newly created Safari folder.
