How To Clear Cache, Cookies and History

What is Cache, Cookies, and History and How Do You Clear Them...

Each time you access a file through your web browser (Internet Explorer, Firefox, Chrome, etc), the browser caches (i.e., stores) it so it doesn't have to keep retrieving the same files or images from the remote web site each time you click Back or Forward. You should periodically clear the cache to allow your browser to function more efficiently.

A cookie is a file created by a web browser, at the request of a web site, that is stored on a computer. These files typically store user-specific information such as selections in a form, shopping cart contents, or authentication data. Browsers will normally clear cookies that reach a certain age, but clearing them manually may solve problems with web sites or your browser.

A browser's history is a log of sites that you visit. When you press a browser's Back button, you are moving back one entry in the history log. Browsers will normally clear history at regular intervals, but you may want to clear it manually for privacy reasons.

See below on how to delete cache, cookies and history for your browser version. To find out what browser version you are on, select the Help button at the top of your browser window and select the About option.
