It's easy to clear the cache on Firefox — whether you choose to do so manually or automatically.

Like all internet browsers, Firefox temporarily stores items (such as images) in a cache to help speed up browsing. If Firefox is your preferred browser of choice, you can choose to clear this cache manually by accessing your "Privacy & Security" tab in the browser preferences. Additionally, you can set up custom settings to clear the cache automatically.

Here's how to do both.
