Focus: Block Websites is a Chrome extension designed to help users maintain productivity by blocking access to distracting websites. The extension allows users to create a customizable block list, ensuring that whenever a blocked site is attempted, a motivational quote is displayed instead. This feature encourages users to stay focused on their tasks while providing a positive reinforcement approach.

In addition to blocking sites, users have the option to take a 10-minute pause or switch to "pause" mode if they need temporary access. The interface is user-friendly, making it simple to add or remove sites from the block list with just one click. Focus: Block Websites is available for free, ad-free, and aims to provide an effective solution for those looking to enhance their concentration while browsing the web.
