Ad blocker for Chrome, Edge and Brave

YouTube without ads.
Videos without interruption.

Pre-roll and mid-roll blocked before they appear. You press play and the video starts — no waiting, no countdown, no “skip ad”.

  • Video ads removed at the source, not hidden afterwards
  • No “Skip ad” and no countdown
  • And across the rest of the web, banners and trackers out of the way

Everything in the way, out of the way

An ad blocker is not just for hiding banners. It is for giving the page back to its reader.

  • Ads and pop-ups

    Banners, interstitials, overlays and those windows that appear when you try to leave. Blocked before they render — not merely hidden with CSS.

  • YouTube without interruptionPro

    Video ads, pre-roll and mid-roll. The video starts when you press play.

  • Trackers and fingerprinting

    Cross-site tracking scripts are cut at the source. Fewer profiles about you circulating out there.

  • Heuristic agentPro

    A new ad that no list knows yet is caught by its behaviour. Protection does not wait for the next update.

  • Lighter pages

    Fewer requests, less JavaScript, less battery. On mobile data the difference shows on the first page.

  • Multiple devicesPro

    Up to 3 browsers on one licence, managed from the panel — switching machines does not cost a new subscription.

Three steps and done

No configuration, no twenty-minute tutorial.

  1. 1

    Install the extension

    One click in your browser store. It works right away, with the default lists already on.

  2. 2

    Accept and start

    The extension opens a screen with the documents, you agree, and your 30 days begin. No sign-up, no card.

  3. 3

    Browse

    Blocking runs on its own. At the end of the 30 days you decide whether to continue — and only then create an account.

An ad blocker that does not watch you

There is a common irony in this industry: extensions that promise privacy and sell your history. Adlessio does not, and the architecture prevents it from doing so.

  • We do not log the pages you visit
  • We do not sell or share data with third parties
  • The device identifier is generated by the extension and holds no personal data
  • No fingerprinting: no canvas, fonts or audio used to identify you
  • Compliant with Brazil’s LGPD and the EU GDPR

Frequently asked questions

Does Adlessio block YouTube ads?

Yes. Video ad blocking is on the Pro plan and covers ads shown before and during playback.

Is Adlessio free?

Every new install gets 30 free days with essential blocking, no card asked. Afterwards you choose to stay free or subscribe to Pro.

Do you collect my browsing data?

No. We do not log the pages you visit or your history. The device identifier is generated by the extension itself and holds no personal data.

Which browsers does it support?

Google Chrome, Microsoft Edge, Brave, Opera and Vivaldi, on Windows, macOS and Linux — one package for all of them. Firefox too, with its own package already signed by Mozilla. Safari is on the way: there the extension must ship inside an app published on the App Store.

Can I use it on more than one computer?

Yes. The Pro plan allows up to 3 simultaneous devices, manageable in the customer panel at any time.

How do I cancel?

In the customer panel, at any time. No penalty and no need to talk to anyone.

What does renewal cost?

$5.99 for the first year. No automatic renewal. Future offers will display their price before purchase.
