Firefox is a free web browser from Mozilla. It is one of the world's most popular browsers, along with Google Chrome and Internet Explorer. In this lesson, we'll talk about how to download and install Firefox to your computer.
Unlike Internet Explorer or Safari, Firefox does not come pre-installed with your operating system. To use Firefox, you must first download and install it on your computer. The process is very simple and should take no more than a few minutes.
If you want to use Firefox as your only web browser, you can set it as your default browser. Review our lesson on Customizing Firefox to learn how.
Firefox offers many of the same features as most web browsers, in addition to its own unique tools. While Firefox is relatively simple to use, you'll need to spend some time becoming familiar with its different features.

Firefox can also be used as a web browser on mobile devices. Available for iOS and Android, the Firefox app allows you to browse the web, open multiple tabs, conduct searches, and more. You'll even have the option to sign in to Firefox on your mobile device, allowing you to sync bookmarks, saved passwords, browsing history, and settings across all of your devices.
