Can a Chrome extension stop me from impulse buying?

Partly. A Chrome extension blocks shopping sites in Chrome, which is where most browser-based impulse buying happens — you open a tab, drift to Amazon, and an hour later there's a cart. Blocking those domains during work or set hours removes the reflex. What an extension cannot do is stop you from buying inside the Amazon or Temu mobile app, or in another browser. For that you need an app-level blocker on your phone or a system-wide Mac tool.

Does blocking Amazon in Chrome also block the Amazon app?

No. A Chrome extension only controls tabs inside Chrome. The Amazon desktop app, the Amazon mobile app, Safari, Firefox, and Arc are all untouched. If you only shop in Chrome on your laptop, an extension covers you. If you tend to grab your phone the moment Chrome blocks you, pair the extension with phone screen-time limits or use the Focuh Mac app for system-level blocking across every browser.

Is there a free Chrome extension to block shopping sites with no account?

Yes. Focuh is free, requires no signup, stores its blocklist locally in Chrome, and collects no telemetry. LeechBlock NG and StayFocusd are also free with no account. BlockSite has a free tier but requires an account and caps you at three blocked sites. If 'free with no account and no site limit' is your bar, Focuh and LeechBlock NG are the two that clear it.

How do I block Amazon, Temu, and SHEIN all at once?

Install a blocker that allows unlimited domains, then add each store as its own entry: amazon.com, temu.com, shein.com, ebay.com, and any others. With Focuh you paste them into the blocklist and start a challenge; all of them are blocked for the duration. Avoid extensions with a 3-site cap for this — fast-fashion and marketplace shopping usually spans more than three domains, so a capped free tier won't hold.

Can I block shopping sites only during work hours?

Yes, with the right tool. LeechBlock NG lets you set time windows per blockset, so Amazon is blocked 9am to 6pm and open in the evening. Focuh uses a challenge model — you start a timed block when you want to focus rather than scheduling recurring windows. Pick LeechBlock NG if you want a fixed daily schedule; pick Focuh if you want to start a clean, distraction-free block on demand and keep it simple.

Will a shopping-site blocker slow down Chrome?

No, not in any way you'll notice. Lightweight blockers like Focuh and LeechBlock NG just check the site you're navigating to against a local list, which is trivial work. Heavier freemium extensions that sync to a server or scan page content can add overhead, but the genuinely free, local-first blockers don't. Blocking Amazon won't make the rest of your browsing slower.

Can a determined shopper bypass a Chrome extension?

Yes. Any Chrome extension can be turned off from chrome://extensions, so someone determined to buy will get there. The value of a blocker isn't being unbreakable — it's adding friction that interrupts the autopilot click. If you need stronger enforcement, the Focuh Mac app blocks at the OS level using Accessibility APIs, which is much harder to switch off mid-session than disabling a browser extension.

Best Chrome Extension to Block Shopping Sites (2026)

Q: What's the best Chrome extension to block shopping sites in 2026?

Focuh is the cleanest free pick. It blocks an unlimited number of domains — Amazon, eBay, Temu, SHEIN, ASOS, whatever your weak spots are — with no account and no 3-site cap. LeechBlock NG is the most configurable if you want schedules and time budgets, but its settings page is dense. BlockSite works but limits the free tier to three sites, which most shoppers blow through immediately. For a no-signup, unlimited-list blocker aimed at impulse spending, Focuh fits best.

Open a tab, "just check a price," and somehow you've spent twenty minutes and forty dollars. If that's your pattern, the best Chrome extension to block shopping sites is the one that blocks every store you drift to — not just three — without making you create an account first. For most people that's Focuh: free, unlimited domains, no signup, and the list never leaves your machine.

This guide compares the Chrome extensions that actually work for blocking Amazon, eBay, Temu, SHEIN, and the rest, and it's honest about the one thing no extension can do: stop you shopping outside Chrome.

Which Chrome extensions block shopping sites?

Extension	Free?	Site limit	Account	Schedules	Best for
Focuh	Yes	Unlimited	None	Challenge-based	No-signup blocking of a long store list
LeechBlock NG	Yes	Unlimited	None	Yes (per blockset)	Fixed work-hours schedules
BlockSite	Trial	3 sites	Required	Paid only	Blocking one or two stores
StayFocusd	Yes	Unlimited	None	Daily time budget	A small daily shopping allowance

The column that matters most for shopping is the site limit. Impulse buying rarely lives at one store. You've got a marketplace (Amazon, eBay), a fast-fashion site or two (SHEIN, ASOS, Zara), maybe a deals app in the browser (Temu, Wish), and a couple of niche habits. A blocker capped at three sites is useless here — you'll hit the wall before you've added your top offenders.

What is Focuh and why does it fit shopping blocks?

Focuh is a free Chrome extension that blocks distracting websites for a focus challenge of any length, from a single afternoon to several months. There's no account, no telemetry, no ads, and no cap on how many domains you add — so you can paste in your entire shopping hit list and block all of it at once.

You add the stores you can't trust yourself around, set a duration, and start. While the challenge runs, those domains won't open in Chrome. When you try, you get a blank wall instead of a checkout page, and most of the time that's enough to break the loop.

Strengths

Unlimited blocklist — add every store, not just three
No account or signup
Local-only blocklist, no tracking
Built for sustained blocks, not just 25-minute sprints

Limitations

Blocks Chrome only — not the Amazon app, other browsers, or your phone
Like any extension, can be disabled from chrome://extensions
No recurring daily schedule; it's start-on-demand

Install Focuh — free, no account.

When does LeechBlock NG make more sense?

If your problem is specifically "I shop during work hours," LeechBlock NG is worth the setup. It lets you build a blockset for shopping sites and attach a schedule — block Amazon and eBay Monday to Friday, 9am to 6pm, open the rest of the time. You can also set a daily time limit, so you get fifteen minutes on shopping sites before they lock for the day.

The cost is complexity. LeechBlock NG's options page is a wall of toggles and dropdowns, and the first configuration takes a little patience. If you want granular control over exactly when stores are available, it's the most powerful free option. If you want to block a list and get back to work in under a minute, it's overkill.

Why BlockSite struggles for shopping blocks

BlockSite is one of the most-installed blockers on the Chrome Web Store, but its free tier caps you at three blocked sites and requires an account. For a focus use case that might be fine. For shopping, three sites is almost never enough — Amazon, Temu, and SHEIN alone use up your entire allowance, and you still haven't blocked eBay, Etsy, or AliExpress.

Everything past three sites — plus scheduling and password protection — sits behind a paid plan. There's nothing wrong with paying for software, but for blocking a long list of stores, a free unlimited blocker like Focuh or LeechBlock NG gets you further without the cap. If you've already hit BlockSite's limit, our free BlockSite alternative covers your options.

How do I block specific stores like Amazon and Temu?

The process is the same in any decent blocker:

Install the extension and open its blocklist.
Add each store as its own domain: amazon.com, temu.com, shein.com, ebay.com, etsy.com, aliexpress.com.
Add the regional variants you actually use, like amazon.co.uk, if you shop on them.
Start the block or set the schedule.

If you mostly fight one store, we have focused walkthroughs for blocking Amazon on Chrome and blocking Temu on Chrome. The principle scales — add as many stores as you need, as long as your blocker doesn't cap the list.

The honest limit: a Chrome extension only blocks Chrome

Here's what no shopping-site extension will tell you upfront: it only controls Chrome. The moment Chrome blocks Amazon, your hand can reach for the Amazon app on your phone, or you can open Safari, or fire up the desktop app. The extension does nothing about any of that.

For browser-based impulse buying on a laptop, that's usually fine — the habit lives in Chrome tabs, so blocking Chrome tabs handles it. But if you know you'll just switch surfaces, you need blocking that doesn't live inside one browser. The Focuh Mac app blocks at the operating-system level using Accessibility APIs, so shopping sites stay blocked across Safari, Chrome, Firefox, and Arc at once, and it's harder to switch off than a browser extension. For phone shopping, pair either tool with your device's built-in screen-time limits.

Which one should you install?

"I want to block a long list of stores, free, no account" — Choose Focuh. Unlimited domains, start in a minute.

"I want to block shopping only during work hours" — Choose LeechBlock NG and set a schedule.

"I only need to block one or two stores and don't mind an account" — BlockSite's free tier covers you.

"I want a small daily shopping allowance, then a lock" — StayFocusd's time-budget model fits.

No extension makes you immune to impulse buying — you can always turn it off. But the friction of hitting a blank page instead of a one-click checkout is often the whole difference between an idle browse and an order you regret. Pick the blocker that lets you add every store you don't trust yourself around, then start the block.
