Is this the foxstart website that shows a series of search engines? If it is you can set a different home page, or restore it to the default Firefox branded Google page, for details see How to set the home page.

Hello. Yes - that's it. I have a tabbed home page set for my local weather forecast. This foxstart.com is in a tab alongside. Up in the right hand corner is the google search window......I'll try the default option to see if that gets rid of it....
