How to Block Roblox on Chrome (Free)

Roblox is built to be hard to leave — endless games, social pressure from friends, and a launcher that drops you straight back in. If it's eating study time or pulling a kid away from homework, blocking it is reasonable. This guide covers how to block Roblox on Chrome for free, starting with a website blocker extension, plus the part most guides skip: the Roblox desktop app a browser block can't reach.

Roblox runs in the browser at roblox.com, so blocking that domain in Chrome stops the web version. But Roblox also has a standalone app, and "block Roblox on Chrome" only ever covers one of those two doors. Here's how to close both.

How to block Roblox on Chrome for free with an extension

The fastest free method is a Chrome extension. The steps are the same across most blockers:

1. Open the Chrome Web Store and install a free website blocker.
2. Add roblox.com to the blocklist.
3. Add www.roblox.com and web.roblox.com to catch the variations.
4. Start the block, or set a schedule if your extension supports one.

Now loading Roblox in Chrome lands on a block page instead of the game.

Watch the site cap. Several free blockers limit you to three sites, and if you're blocking games you'll usually want Roblox alongside others — Fortnite's site, Minecraft, browser game portals like CrazyGames or Poki. Focuh is a free Chrome extension with no account and no site limit, so you can block the whole list at once. If you want to compare which free blockers cap you and which don't, our best free website blocker for Chrome guide breaks it down.

Why the Chrome block won't stop Roblox on its own

Here's the honest limit. A Chrome extension blocks Chrome tabs — that's the whole of what it can do. Roblox has a desktop app on Windows and Mac that launches games without ever opening a browser. Click "Play" and the app takes over; the extension never sees it.

So a Chrome extension alone leaves two ways back in:

• The Roblox desktop app, which bypasses the browser entirely.
• Other browsers — Safari, Edge, Firefox — where the extension doesn't exist.

And if you're blocking Roblox for a child rather than yourself, there's a third gap: any extension can be switched off from chrome://extensions, and kids work that out fast.

This doesn't mean the extension is pointless — for an older student using it as a self-control nudge, it's often enough. But for real parental control or a hard block, you need more than Chrome. Our explainer on system-level vs browser website blocking covers exactly where a browser block holds and where it leaks.

How to block Roblox for a child on Chrome

If this is about a kid, use Google Family Link instead of a plain extension. A supervised account is far harder to bypass:

1. Set up your child's Google account as a supervised account in Family Link.
2. Sign them into Chrome with that account.
3. In Family Link, go to website restrictions and block roblox.com.

A child can't disable a Family Link restriction without your passcode, unlike an extension they can toggle off. For full coverage, also use Family Link's app controls (or your operating system's parental controls) to block or remove the Roblox desktop app, and apply restrictions at the device level so other browsers are covered too.

How to block Roblox everywhere on a Mac

If you want Roblox genuinely gone — every browser plus the app — block it at the operating-system level. A system-level blocker covers Chrome, Safari, Firefox, and the rest in one move, and the better ones block native apps too.

Options on a Mac:

• Focuh for Mac — free. Blocks the roblox.com website across every browser and blocks the Roblox app at the system level, so both doors are closed. It ties blocking to focus sessions, which suits study hours: Roblox is gone while you work and back during a break.
• SelfControl — free and open-source. Blocks websites only (not apps), but once a block starts you can't end it until the timer runs out. Good for an older student who wants a self-imposed block they can't cheat.
• Cold Turkey — paid, with strong locking and app blocking if free tools keep getting bypassed.

The Focuh Chrome extension and the Focuh Mac app are both free and built to work together — the extension handles Chrome, the Mac app handles the app and every other browser. Download Focuh for Mac if the browser block alone isn't holding.

Blocking Roblox during study hours, not all day

A blanket all-day block often backfires — it turns Roblox into forbidden fruit and invites a workaround. Tying the block to specific times tends to stick better.

If your Chrome extension supports scheduling, set Roblox to block during school or homework hours and open up afterward. If it doesn't, the Focuh desktop app uses a session model instead: start a focus session, Roblox is blocked for its duration, and it lifts automatically when the session ends. That makes the block part of a study routine rather than a punishment, which is an easier sell to a teenager — and to yourself.

Which method should you use?

Block Roblox in Chrome right now, just for yourself — a free extension with no site cap. Add roblox.com and you're done in a minute.

Block Roblox for a younger child — Google Family Link supervised account, plus device-level controls for the desktop app.

Stop Roblox completely, app included — a system-level blocker on the Mac. Focuh blocks the site across browsers and the app; Cold Turkey if you need harder locking.

Self-control for an older student — SelfControl's irreversible timer, or Focuh's session-based blocking tied to study time.

A Chrome extension is the right first step, and for some people it's the only step they need. Just go in knowing what it can't do: it won't stop the Roblox app, and it won't follow Roblox into another browser. Close those gaps and the block actually holds.

Install the free Focuh Chrome extension to block Roblox in Chrome with no account or site cap. Or get the free Focuh Mac app to block the website across every browser and the Roblox app too.
