Do not share your User ID and password with anyone else. Do not leave your computer unattended while the browser is still running. Empty your disk cache at the end of your Web session. To do this, select the menu item that allows you to empty disk cache. Set your disk cache to 0.
All Web browsers have a default setting that caches their Web activity.
This means your browser copies the information you see on-screen, like graphics and text files, to the memory and hard disk of your computer. Once loaded into your cache, the browser no longer has to download the information through the Internet, which makes revisiting a Web site or exploring a new Web site faster. Other people who access your computer can access the disk cache and may be able to view the contents of your previous Web activity. You can set your disk cache to 0 to ensure nothing is stored on your hard disk. You won't be able to access previously viewed pages as quickly, but your security will be enhanced.
