About this extension

Blocks ads, trackers, cookie banners and even promoted posts on X, Reddit, LinkedIn and VK.

Read the publisher’s full description

``` SupafastBlock is a fast, lightweight ad blocker for Chrome that removes ads, popups, trackers and cookie banners on every website you visit. Pages load faster, look cleaner and stop following you around the web. Unlike most ad blockers, SupafastBlock also hides native sponsored content: promoted posts and sponsored feeds on X (Twitter), Reddit, LinkedIn and VK that normal network blocking cannot reach. WHAT SUPAFASTBLOCK BLOCKS - Banner ads, video ad scripts, popups and pop-unders on all sites - Trackers and analytics scripts with 84,000+ AdGuard filter rules (worldwide and Russian filter lists) - Promoted posts and sponsored content on X (Twitter), Reddit, LinkedIn and VK feeds - Cookie consent banners, newsletter popups and chat widgets (optional one-tap toggle) - URL tracking parameters such as utm_*, fbclid and gclid - Yandex Direct and Adfox ad banners on any website KEY FEATURES - Element Zapper: click any annoying element on a page to hide it forever, just like in developer tools - Per-site allowlist: support your favorite sites by disabling the ad blocker for them with one tap, synced across your devices - Privacy report: see exactly which tracker companies (Google Ads, Meta, TikTok, Yandex and more) were blocked on the current page - Live statistics: blocked requests today, this week and all time, plus estimated traffic and loading time saved - Blocked counter badge right on the toolbar icon - English and Russian interface WHY CHOOSE SUPAFASTBLOCK - Fast and lightweight: built on Manifest V3, the modern Chrome extension platform. Filtering runs inside the browser engine, not in heavy scripts, so it uses almost no memory or CPU - Private by design: no data collection, no accounts, no remote code. All filter rules ship inside the extension and nothing is downloaded or sent anywhere - Works out of the box: install, pin the red shield and browse without ads. No setup needed - Honest blocking: clear per-site controls instead of hidden "acceptable ads" deals HOW TO USE 1. Install SupafastBlock and pin the red shield icon to the toolbar 2. Browse: ads, popups and trackers are blocked automatically 3. Click the shield to see stats, hide annoyances, zap elements or allowlist a site PRIVACY SupafastBlock collects no user data at all. Your settings stay in your own Chrome profile. Privacy policy: https://supafast.tech/en/supafastblock/privacy SupafastBlock is the simple, modern adblock for people who want a clean, fast and private web without configuring anything.
