FocusBlocker is a Chrome add-on developed by shing.lyu that helps users stay focused on their work or studies by blocking time-wasting websites. Unlike traditional schedule-based blockers, FocusBlocker offers more flexibility in blocking websites.

With FocusBlocker, users can set a timer for a specific duration, such as 10 minutes, and freely browse the internet during that time. However, when the timer runs out, the add-on automatically blocks blacklisted websites for a configurable duration of 50 minutes. This feature ensures that users are unable to access distracting websites and can maintain their focus on important tasks.

This lightweight add-on is perfect for individuals who have a flexible working schedule. Instead of being bound by a fixed blocking schedule, users can control when they want to block websites, allowing them to adapt to their specific needs.

For Firefox users, there is also a version of FocusBlocker available on the Firefox Add-ons website.

FocusBlocker is a free add-on that can significantly improve productivity by preventing time-wasting on websites during work or study sessions. Try it out and experience the benefits of focused and uninterrupted work.
