BlockZee stops ads, trackers, and fingerprinting scripts — silently, before they reach you. Works on every browser you use.
No subscription. No data collection. Just privacy.
Hundreds of invisible scripts record every click, scroll, and pause — then sell that data to advertisers you've never heard of.
Look at a pair of shoes once and see ads for them everywhere for weeks. That's not a coincidence — it's a surveillance system.
Up to 40% of page load time is ad and tracker scripts loading. They drain your battery and eat your data — without your permission.
16 independent features. Turn any of them on or off in one click.
Kills YouTube pre-rolls, overlay ads, banner ads, promoted feed items, and 200+ ad networks — before they even load. YouTube videos play instantly.
Stops Google Analytics, Facebook Pixel, Hotjar, Segment, Mixpanel, and 50+ other trackers from collecting your behavior.
Scrambles Canvas, AudioContext, and WebGL signals so you look like a different person to every site.
Seals the hole that lets websites find your real IP even when you're using a VPN.
Automatically deletes tracking cookies when you close a tab, so advertisers can't follow you between sessions.
Strips hidden tracking codes from URLs — utm_source, fbclid, gclid, and 50+ more — before they reach your history.
Blocks the invisible background reports websites send about your behavior to Microsoft, Sentry, Datadog, and others.
Automatically switches insecure HTTP connections to encrypted HTTPS wherever possible.
Hides Shorts, sidebar recommendations, end cards, and merch shelf. Disables autoplay. Just the video.
Hides where you came from when clicking a link, so sites can't track your browsing path.
Click Add to Browser. No account, no signup, no credit card. It's just there.
The moment you open a tab, Blockzeee is already blocking ads and trackers before the page loads. You don't have to do anything.
Click the shield icon anytime to see exactly what was blocked on the current page — ads, trackers, fingerprinting attempts, and more.
We don't cut corners on privacy or features.

Blockzeee works entirely inside your browser. It never sends data to our servers, never phones home, never builds a profile on you. We couldn't track you even if we wanted to — there's no server to send it to.
Blockzeee is independently built and privately maintained. No VC funding, no corporate ownership, no conflict of interest — just a tool that does what it says.
Pick your browser. Click install. You're protected.
Already have it? Leave a review — it helps more people find it.
Yes — whitelist your password manager's domain. Blockzeee's fingerprint protection randomizes browser signals that password managers use to recognize your device. Without whitelisting, your password manager may not recognize you and keep asking you to verify via email every time you log in.
The same applies to your bank and any site that sends "new device detected" emails.
lastpass.com, 1password.com) and click AddBlockzeee will be fully disabled on that site only. Everything else stays protected.
Turn off Cookie Cleaning. Blockzeee's cookie cleaning feature automatically deletes cookies when you close a tab — which includes the login cookies that keep you signed in. When you reopen the site, it has no record of you and asks you to log in again.
Everything else — ad blocking, tracker blocking, fingerprint protection — keeps running. Only cookie deletion is disabled.
Alternatively, if you only want to stay logged into one specific site, add it to the Whitelist tab instead. That disables all Blockzeee features on that site only.
Click the Blockzeee shield → hit Pause Protection. If the site works after that, click the Whitelist tab and add the domain. Protection resumes automatically on every other site.
It makes your browser faster. Ad and tracker scripts are blocked before they download, which removes 20–40% of the data a typical webpage loads. Pages render quicker and use less memory.
No. Blockzeee runs entirely inside your browser and never sends any data anywhere. It has no server, no account system, and no analytics. Everything stays on your device.
No. Blockzeee removes ads and sponsored content without touching the video player. Videos play normally — just without pre-rolls, overlays, or the promoted junk in your feed.
No catch. No ads inside the extension, no selling your data, no premium tier. Just free, forever. We built this because we were tired of being tracked — same reason you're here.
