How to Clear Cache in Firefox

“Cache” refers to all the data on web pages viewed through a browser. The cache stores information about images, videos and any other content of websites. It helps to make your browser run faster. If the page you want to view is already in the cache, the browser instantly downloads it from your hard drive.

The cache should be periodically cleaned to free up memory on your hard disk. Clearing cache also helps to display pages correctly,  for example, if some changes in design have been made. In this article we will tell you how to clear the Firefox cache. If you use Safari or Google Chrome, read our previous article How to delete browsing history.
