How do I block Threads on Chrome for free?

Install a free Chrome blocker, add threads.net to the blocklist, and start a focus session. The Focuh extension does this with no account and no cap — open the icon, paste threads.net, pick a challenge length, and the tab is blocked for the whole stretch. When you reach for it out of habit, you hit a quiet page instead of the feed. It takes under a minute and stays free, with no paid tier waiting to upsell you.

Does blocking threads.net also block the Threads app on my phone?

No. A Chrome extension only controls tabs inside Chrome on your computer. It cannot touch the Threads app on your iPhone or Android, and it cannot block Threads in Safari, Firefox, or Arc. If your scrolling happens on your phone, the honest fix is the phone's own Screen Time or app limits. A Chrome extension solves the desktop-browser slice of the problem, which for many people is where work-time scrolling actually happens.

Why does Threads keep pulling me back even after I close the tab?

Threads, like most feeds, is built around variable rewards — you never know if the next post is worth it, so you keep checking. Closing the tab does nothing about the reflex to reopen it. A blocker breaks the loop by making the reopen fail: you type the URL, hit a block page, and the urge passes in a few seconds. Over a week of that, the automatic reach-for-Threads habit weakens because it stops getting rewarded.

Can I block Threads only during work hours?

Some blockers offer scheduling, but Focuh takes a different approach: instead of daily windows, you block Threads continuously for a challenge of 30, 91, or 180 days. The idea is to remove the habit rather than ration it. If you genuinely need Threads for work and only want it gone during focus blocks, a scheduling extension like LeechBlock NG fits better. For most people, continuous blocking sticks harder than a daily on-off window.

Will blocking Threads in Chrome slow down my browser?

No. A lightweight blocker only checks the hostname of a tab against your local list when you navigate, which is negligible work. Focuh stores your blocklist in local Chrome storage and runs no remote code, so there's nothing phoning home to add lag. The extensions that slow browsers down are the heavy freemium ones that scan page content or sync to a server, not a simple domain blocker doing one cheap check per page load.

Can I get around the Threads block if I really want to?

Yes — any Chrome extension can be disabled from chrome://extensions, so a determined person always can. The point isn't to be unbreakable; it's to add enough friction that the autopilot reach fails. If you keep disabling it, that's a sign you need OS-level blocking. The free Focuh Mac app uses macOS Accessibility APIs and doesn't sit in the extensions page, so switching it off mid-session takes real, deliberate effort instead of two clicks.

Is the Focuh Threads blocker actually free?

Yes, genuinely free. There's no paid tier, no account, no email signup, and no telemetry. You can block threads.net and as many other sites as you want with no cap. Your blocklist and attempt counter stay in local Chrome storage and never leave your device. That's different from blockers that call themselves free but limit you to three sites or require a login — Focuh has no asterisk on the word free.

What's the best way to block Threads everywhere, not just Chrome?

Pair the free Chrome extension with the free Focuh Mac app. The extension blocks threads.net in Chrome tabs; the Mac app blocks at the operating-system level, covering Safari, Firefox, Arc, and native apps during a focus session. Together they close the gap where you'd otherwise switch browsers to sneak a look. For phone scrolling, add your device's built-in app limits, since no desktop tool can reach the mobile app.

How to Block Threads on Chrome for Free (2026)

June 18, 20268 min readFocuh

If Threads has become the tab you open without deciding to, the fastest fix is a free Chrome extension: add threads.net to a blocklist, start a focus session, and the site stops loading. To block Threads on Chrome for free, you don't need a subscription or an account — the Focuh extension blocks it during a self-imposed challenge with no cap and no signup. Here's how to set it up, and where a browser extension stops being enough.

How do you block Threads on Chrome for free?

Three steps, under a minute:

Install the free Focuh extension from the Chrome Web Store. No account, no email.
Open the icon and add threads.net to your blocklist. Add www.threads.net too if you want to be thorough.
Pick a challenge length — start with 30 days — and begin. Threads is now blocked in every Chrome tab for the whole challenge.

When you reach for Threads out of reflex, the tab hits a quiet block page instead of the feed. Focuh also counts the attempt, so you can watch how often you tried to open it. Seeing "you reached for Threads 22 times Monday, 6 times Friday" is concrete proof the habit is fading.

Why a Chrome extension can't block Threads everywhere

Be clear-eyed about what a browser extension does and doesn't do. It blocks tabs inside Chrome on your computer. That's the whole boundary. It cannot:

Block the Threads app on your iPhone or Android
Block Threads if you open it in Safari, Firefox, or Arc
Block Threads on a different computer
Survive a quick trip to chrome://extensions to disable it

For a lot of people, that's fine — desktop work-time scrolling happens in Chrome, so blocking Chrome covers the moment that matters. But if you catch yourself switching to Safari the second Chrome blocks you, the extension alone won't save you. You need blocking a layer deeper.

Where you scroll Threads	Does a Chrome extension block it?	What does
Chrome tab on your laptop	Yes	The Focuh extension
Safari or Firefox on the same Mac	No	The Focuh Mac app (OS-level)
Native desktop app	No	The Focuh Mac app
Threads app on your phone	No	Your phone's Screen Time / app limits

What if you just open Threads in Safari instead?

This is the honest weak point of every browser extension, and it's worth saying plainly: if blocking Threads in Chrome only pushes you to Safari, you've moved the problem, not solved it.

The fix is OS-level blocking. The free Focuh Mac app blocks websites and apps at the operating-system level using macOS Accessibility APIs, so a blocked site stays blocked across every browser on the machine during a focus session — Chrome, Safari, Firefox, Arc, all of them. It's also much harder to switch off mid-session, because it doesn't live in the extensions page where one toggle ends the block.

The most reliable desktop setup is both: the free Focuh Chrome extension for in-browser blocking, plus the free Mac app for everything else. Neither costs anything, so running both is free. For the full breakdown of why this matters, see system-level vs browser website blocking.

Should you block Threads on a schedule or continuously?

Two philosophies, and the right one depends on your relationship with the app.

Continuous blocking removes Threads for a long stretch — 30, 91, or 180 days. You're not rationing access; you're letting the habit starve. This is what Focuh is built for, and it tends to stick better because there's no recurring window where the "quick check" sneaks back in.

Scheduled blocking allows Threads outside set hours — say, blocked 9am to 5pm, open after. This fits people who genuinely use Threads for work or community and only want it gone during deep work. If that's you, a scheduling extension like LeechBlock NG handles it well; for a comparison of free Chrome options, see the best free website blocker for Chrome.

Most people who search for how to block Threads aren't trying to manage it carefully — they're trying to stop the reflex. For that, continuous wins.

How blocking Threads compares to a Pomodoro timer

A common alternative is a Pomodoro extension that blocks sites only during work intervals, then unblocks on breaks. That's a different model: blocking tied to a timer rather than a commitment. The catch is that the break is exactly when the quick Threads check sneaks in and eats twenty minutes.

If you already think in Pomodoros, the timer approach can work. If you'd rather the app simply be gone, continuous blocking is cleaner. For a side-by-side on the two models, see Focuh vs Strict Workflow, which compares a continuous challenge blocker against a classic Pomodoro blocker.

What about blocking other distractions while you're at it?

Threads is rarely the only tab. If you're blocking it, you're probably also losing time to X, Instagram, Reddit, and the rest of the feed economy. Add them to the same blocklist in one go — Focuh has no cap, so there's no reason to block one site at a time. A blocklist of seven distractions is no harder to set up than one.

For a fuller approach to the whole category, how to block social media on Chrome for free walks through blocking the major feeds together, which is usually more effective than picking them off individually.

The honest bottom line

To block Threads on Chrome for free: install the Focuh extension, add threads.net, start a challenge. It takes under a minute, costs nothing, and requires no account. That handles Chrome.

What it won't do is block Threads in other browsers, in the desktop or mobile app, or stop someone determined to disable it. If your scrolling jumps to Safari or a native app the moment Chrome is blocked, add the free Focuh Mac app for OS-level blocking that covers the whole machine. And for the phone — where a lot of Threads time actually lives — lean on your device's built-in app limits, because no desktop tool can reach it.

Install Focuh for Chrome — free, no account. Or get the free Mac app to block Threads across every browser on your computer.
