Website Blocker: MT by Maxim Topciu

Stay focused with a simple list of websites you want to avoid.

Website Blocker: MT redirects distracting websites to a reminder page so you can get back to what you were doing.

• Open settings from the toolbar popup and add a website to block.
• Choose indefinite blocking, 15, 30 or 60 minutes, or custom whole minutes.
• Edit a saved website while keeping its blocking state and deadline.
• Switch blocking off or on for each website without deleting its entry.
• Remove a website whenever you want to allow it again.
• Keep your block list and unexpired deadlines across browser restarts.

Timed entries disappear from the visible list when their deadlines pass. Turning blocking off does not pause or reset the timer. After expiry, navigate or reload to open the website again; an existing reminder page stays open.

Website matching ignores a leading www. Other subdomains can be added separately. This is a lightweight focus tool with one-time durations; it does not provide recurring schedules, passwords, or parental controls.

The interface supports 40 languages. The newer duration controls, duration errors and loading message currently appear in English.

Your block list, blocking states and deadlines are stored in the browser's built-in sync storage and may sync between your devices if Firefox Sync is enabled. Blocking decisions happen in your browser. The developer does not receive your list or browsing history. There are no ads, analytics, or paid features.
