Focus Blocker is a Chrome extension that serves as an internet filter, allowing users to block millions of websites based on specific categories. This tool is particularly useful for individuals looking to enhance their productivity by minimizing distractions during work or study sessions. In addition to website blocking, it offers the capability to restrict access to YouTube videos and subreddits, tailoring the browsing experience to align with the user's focus needs.

This extension is designed to work exclusively with the accompanying desktop application, ensuring that if the extension is disabled or removed, access to the browser may also be restricted. Focus Blocker is available for free, making it an accessible solution for anyone seeking to manage their online activities effectively.
