Another possible solution that would work in most browsers is to write yourself a little HTML page and save it locally. In the page have some javascript that selects the 'home page' you want either randomly or based on the date/time.
If you wanted to be really fancy you could save the page in the chrome and use a cookie to keep track of the 'homepage' you last visited so that you always get the next page in the sequence.
