Modify request and response headers. No ads, no malware.

Features & Capabilities

Adblocker Zero removes ads and trackers from the web. No account, no setup, nothing to configure - install it and pages immediately load cleaner, faster and more private.

WHAT IT BLOCKS • Banner ads, pop-ups, sticky overlays and sponsored clutter • Ad and tracker requests — stopped before they ever leave your browser • Trackers that follow you from site to site • Includes defenses against anti-adblock scripts

WHY ADBLOCKER ZERO • Truly lightweight: blocking runs on your browser's built-in engine, so there is no heavy background process slowing you down • Private by design: no account, no telemetry, no data collection - your browsing history never leaves your device • Free and open source (MIT license) • Available in 52 languages

EVERYDAY CONTROLS • One switch to pause blocking everywhere • A per-site switch to trust sites you want to support • A live counter of blocked requests • Filter lists refresh automatically every day

FOR POWER USERS • "My filters": add your own rules in EasyList-compatible syntax • Manage your trusted-sites list • Built on proven, community-maintained filter lists: EasyList, EasyPrivacy, Peter Lowe's list and more

PERMISSIONS, EXPLAINED Adblocker Zero asks to read and change data on the websites you visit. That permission is used for exactly one thing: blocking ad and tracker requests and hiding ad elements on the page. The extension collects nothing and sends nothing; the only network requests it makes are the daily downloads of the public filter lists.

Is Adblocker Zero Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Adblocker Zero requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Adblocker Zero is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
