Clearing your cache and cookies

Clearing your cache and cookies can significantly improve your browser's performance. It is particularly helpful if you have persistent problems with pages not loading as expected when using databases. These problems are often caused by your browser calling up old information from your cache or cookie folder. Clearing them usually solves the problem.
