How to Block Facebook on Chrome (in ways that actually stick)

Facebook invented the infinite scroll feed and the red notification badge, and both still work on you. Even people who 'don't use Facebook anymore' lose time to it through Marketplace, Groups and event pages, each of which exits into the News Feed by design. Every path through Facebook is routed through the slot machine.

Option 1: Block Facebook manually (free, but you hold the keys)

Chrome has no built-in "block this website" button for normal installs, so the manual route means editing your computer's hosts file: point the domain at 127.0.0.1 and the site stops resolving. It costs nothing and needs no software.

Lots of people need Marketplace or a Group for legitimate reasons, which makes the all-or-nothing domain block a constant negotiation with yourself. Messenger.com is a separate domain that survives most Facebook blocks.

The deeper problem is structural: any block you can set up in two minutes, you can undo in thirty seconds, and the moment you'll want to undo it is precisely the moment it exists for. Manual blocks are honor-system locks.

Option 2: A list-based blocker extension

Extensions like BlockSite or StayFocusd let you add the domain to a list, which beats the hosts file on convenience. Two weaknesses remain: the list is binary (the whole domain is blocked even when part of it is genuinely useful for your work), and the off switch is two clicks away in your extensions menu. List blockers stop the absent-minded visit; they rarely survive a motivated one.

Option 3: Block Facebook with an AI that knows what you're working on

Focus AI works differently: you type what you're doing ("finish the calculus problem set"), pick a duration, and lock in. During the session, the AI reads every page you open against that task. Facebook gets blocked when it doesn't serve the work, and the block page shows your own promise back to you, with an escape-attempt counter and a running tally of the time you've saved.

1. Install Focus AI from the Chrome Web Store (free, no account needed).
2. Type the task you're actually here to do and choose a session length.
3. Click Lock me in. Facebook now hits a wall for exactly that long, and quitting early means typing your surrender letter by letter.

Two details matter for social feed sites specifically: the AI evaluates pages rather than domains, so the useful corners of the internet stay reachable while the feed does not. And every time you walk away from the block page, the win is stamped and timed: resisting Facebook becomes a streak you can watch grow instead of a sacrifice you silently endure.
