If you want to make sure your browser is constantly getting the most recent content (i.e. refreshed regularly), you can either manually hit the refresh button every time you view the page, or try this Web Page Refresher program. Personally I like to have my baseball box scores updated constantly, so this simple program does the trick for me.

So if you want to make sure you are seeing the latest box scores, stock quotes, forum posts, etc. then give this utility a try.
