Firefox's Block Site Feature Explained - How to Block Websites

If you’ve ever had to block websites for various reasons, like stopping students from viewing Facebook during class or preventing coworkers from wasting time at work, this article is for you. This guide will walk you through Firefox’s “Block Site” feature and show how to set up website blocking rules on your computer.

If you want to view a blocked website, you’ll have to unblock it using the “Block Site” settings. You can unblock a single website or unblock all the websites you’ve blocked at once. It helps prevent unrestricted browsing, which can lead to time wasted on social networking sites.
