ProBlocker Features:
Ads, Trackers, Pop-ups, and Malware
ProBlocker cancels ad and tracker requests at the network level,
before they reach your browser.
No content downloads. No hidden ads. No exceptions.
YouTube Ad Blocking
Pre-roll, mid-roll, overlay banners, and bumper ads are cancelled before a single byte downloads. The video plays immediately — no skip button needed.
YouTube ad blocking details →Network-Level Blocking
Requests are cancelled via Chromium's native declarativeNetRequest API or Firefox's webRequest API before any data transfers. This guarantees faster page load times, lower memory usage, and reduced bandwidth on every site.
Cryptocurrency Mining
Some websites run background cryptocurrency mining scripts (cryptojacking) that hijack your device's CPU, causing slow speeds and battery drain. ProBlocker blocks these scripts immediately, keeping your hardware running cool and efficient.
Malware and miner protection →Malware Protection
Malvertising networks inject malicious code into legitimate ad creatives. ProBlocker blocks requests to known malware distribution domains and scam endpoints before they load, preventing drive-by downloads and browser exploit attempts.
Malware protection details →Pop-up Blocking
Forced redirects, pop-unders, and overlay dialogs never get the chance to open. ProBlocker intercepts script-initiated window openings and tab redirects before they can hijack your browsing session.
Pop-up blocking details →Tracker Blocking
Online trackers shadow you across the web to build a behavioral profile. ProBlocker stops tracking beacons, analytics scripts, and social widgets at the network level, keeping your search history and identity completely private.
Tracker blocking details →All Ad Formats Blocked
From video-ad protocols like VAST and VPAID to traditional display banners, native sponsored posts, text ads, and audio commercials. ProBlocker matches requests against comprehensive rulesets, leaving pages clean and distraction-free.
Supported platforms →No Acceptable Ads Whitelist
Many ad blockers participate in paid whitelists (like the "Acceptable Ads" program), allowing certain advertisers to pay to bypass the filter rules. ProBlocker blocks every match, with zero paid exemptions, zero whitelisting, and no exceptions.
