‘In order to speed up web browsing, browsers are designed to download web pages and store them on your computer in an area called the cache (pronounced cash). When you visit the same page for a second time, the browser speeds up the display time by loading the pages locally from the cache instead of downloading everything again. This sometimes results in less than current versions of web pages being displayed, along with problems on registration and authentication pages.
Over time, this process may actually begin to slow down your browser as large amounts of data are saved to your hard drive. A cache does not empty itself and anyone who gains access to your computer can tell from these files what websites you have visited. To make matters worse, this caching is not limited to pages, but can also include login IDs, passwords, banking information, and other sensitive information.
Clearing your cache can significantly improve the speed and performance of your browser and ensures that anyone who uses the same computer and browser after you (particularly on public computers) will not see your private information. It’s a good habit to clear your cache from time to time.’
