Blocks Ads Site-Wide
Requests to 90+ known ad and tracker networks — Doubleclick, Googlesyndication, Taboola, Outbrain, Criteo, and more — are blocked before they load, on every website.
SaifBlock — Block Ads and Trackers Everywhere
A free browser extension that blocks ads and trackers on every website you visit, before they ever load. Built for Chrome, Edge, and Firefox.

🛡️ What It Does
Built for Real Browsing, Not Just a Demo
🛡️
Stops Trackers Following You
Analytics beacons, fingerprinting scripts and retargeting pixels are blocked alongside the ads, so the sites you visit cannot build a profile of you across the web.
🧩
Hides Banner & Sponsored Boxes
Common ad-slot and sponsored-content containers are hidden with cosmetic filtering, so pages stay clean even where network blocking alone isn't enough.
🎚️
One-Click On/Off
Toggle the whole extension, or just pause it on the one site that needs it — from the toolbar icon, no settings menu required.

🦊 Firefox note: loading it as a "Temporary Add-on" is instant but resets when Firefox restarts. For a permanent install, submit the downloaded zip at addons.mozilla.org (free account, "On your own" / unlisted distribution) — Mozilla signs it automatically in a few minutes and gives back a .xpi file you can install permanently by dragging it into Firefox.
Good to Know
Honest Limitations
📋
Curated List, Not Everything
Uses a hand-picked list of 90+ ad/tracker domains rather than a full EasyList — most ads are caught, but a brand-new ad network may slip through occasionally.
💻
Desktop Browsers Only
Chrome, Edge, and Firefox on desktop don't support the same extension system on mobile, so there's no mobile app version of SaifBlock.

If a Site Breaks
Click the toolbar icon and choose "Turn off on this site" — useful if a login form or checkout page stops working.
