In this tutorial, we learn how to clear the cache on your browser. This is one of the most important things on your browser and should be cleared every so often so it doesn't fill up your hard drive. To clear this out, you will first need to open up Firefox. After this, you will go to the top of the screen and click on the tools. From here, go to the privacy tab. Click on the options for the history you want cleared out and then choose if you want your cookies cleared out. Next, you can click to clear everything and you're done!
For help on other platforms and browsers, see "How to Clear Your Cache on Any Web Browser" for details.
