Change your home page to a non-firefox one. If you want google as your home page, do the following:

1. Go to google.com
   
   
2. Click the Firefox button, go to Options | Options | General.
   
   
3. Make sure it says "Show My Home Page" in the dropdown menu at the top and then click the button called "Use Current Pages".
   
   

I can't think what Mozilla is trying to achieve by displaying that childish junk.
