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.

Solution 1:

Two options come to mind:

1. Reset Safari (in Safari menu), restart the application and try again
2. 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.
