How to Block a Website in Firefox?

Do you want to block a website in Firefox? Some sites do have irrelevant and offensive content and we don’t want to visit such sites or if any of your younger sibling or your child is wasting too much time on the internet. Then blocking sites with irrelevant content becomes important.

Well, if you are using the Firefox web browser, then let me tell you it doesn’t have an inbuilt feature to block websites. On the way, it allows installing add-ons or extensions which would help in blocking the websites. ‘Block Site’ is a popular add-on which you can add to your Firefox browser.

We also have another method in which you can edit a host file in Windows to block a website. In this section, we will discuss both these methods.
