Web Block is a Chrome extension that allows you to easily block unwanted websites. Developed by Jacob, this free extension falls under the category of Browsers and the subcategory of Add-ons & Tools.

Web Block lets you create and manage lists of websites. When you navigate to a website that is on one of your lists, it will redirect you to a block page, effectively preventing you from accessing the site. There are two types of lists available: Block lists, which block the websites on them, and Allow lists, which allow only the websites on them while blocking everything else.

One interesting feature of Web Block is the ability to set timers for your lists. These timers keep track of how long you are breaking the rules of the list, and once the time is up, the website will be blocked again.

Please note that Web Block is currently in beta, which means it is still under active development and may have some missing features and bugs. However, it provides a useful solution for those who want to control their website browsing habits.
