Cisdem Web Blocker by Cisdem Inc

Easily distracted by your favorite websites and want to stay focused and productive? Want to make Firefox child safe and prevent inappropriate sites from being opened? This extension can block websites for you. It prevents you from wasting time on distractions like YouTube and keeps children from web content that you think is bad, harmful, or dangerous.

You can block the current website with a click. You can also go to the Block List tab to add specific sites and block them. In addition to entire websites, this site blocker lets you add web pages to the Block List. You can disable/enable the blocking of a site by deselecting/selecting the checkbox, and remove a site by clicking the Remove icon next to it.

To enjoy more useful features, such as blocking only at scheduled times, protecting blocking with password, blocking websites by category, blocking URLs with certain keywords, and blocking all sites except a few, you can use Cisdem AppCrypt. Learn more at https://www.cisdem.com/appcrypt.html.
