5 Best Facebook Blocker Extensions to Reclaim Your Focus—
In a world of endless notifications and attention-grabbing feeds, Facebook can quickly become a productivity sink. Browser extensions that block or restrict Facebook help you reduce distractions, lower phone and desktop time, and rebuild focus. Below are five highly effective Facebook blocker extensions, how they work, pros and cons, and tips to get the most from them.
What to look for in a Facebook blocker extension
- Customization options — ability to block the feed, notifications, or the entire site.
- Scheduling — set work hours or focus sessions when Facebook is blocked.
- Whitelist/blacklist — allow certain pages (work groups) while blocking others.
- Nudges and timers — gentle reminders or strict locks depending on needs.
- Cross-device sync — useful if you want consistent blocking across browsers and devices.

Setup tips to reclaim focus
