To update Internet Explorer, simply run your regular Windows Updates, or let Automatic Updates restart your computer when you are prompted. Internet Explorer will be updated by DePaul's Windows update process or, on a personal computer, by Microsoft's Windows update process.
Firefox usually auto-updates itself. However, you can manually check for updates by doing the following:
1. Open Firefox.
2. Click on the Orange Firefox Button in the top left, then go to Help -> About Firefox.
3. If there is a Check for Updates Button, then click it. Otherwise, your Firefox browser is up to date.

Google Chrome automatically updates your browser when it detects a new version. The update process doesn't require any action on your part.
