Last week Mozilla released Firefox 2.0.0.5 which corrected a number of security vulnerabilities. Firefox is very good about prompting you to update your browser as long as you are already using version 2.0.x.x. If you are not sure which version you have, from within Firefox go the Help menu and select About Mozilla Firefox. If you have version 2, but it is earlier than 2.0.0.5, then go to the Help menu and select Check for Updates.... If you are still using version 1 or 1.5, go to www.mozilla.com to download the latest version. Keeping your web browser and OS patched is one of the most important steps you can take to protect your computer.
