About this extension
Stop fighting slow, ad-cluttered pages and endless "Accept All" cookie walls. SWEEPR Deepblock is a next-generation ad blocker, automatic cookie consent rejector, scam storefront detector, and background tab RAM optimizer engineered to make Firefox feel brand new—with zero page-load lag.

Unlike bloated legacy extensions that sell out to "Acceptable Ads" whitelist programs or run heavy background parsers on every tab, SWEEPR Deepblock blocks ads, trackers, and cryptominers at the network edge before they ever download.

WHY USERS SWITCH TO SWEEPR DEEPBLOCK
  • Zero-Lag Video & Display Ad Blocking: Silences intrusive video pre-roll/mid-roll ads, floating autoplay players, popunders, and high-CPU display banners. Automatically strips invisible tracking parameters (utm_*, fbclid, gclid, msclkid) from links.
  • Automatic Cookie Banner "Reject All" (<50ms): Never click "Manage Preferences" again. Automatically selects "Reject All" or "Necessary Only" on GDPR/CCPA consent popups (OneTrust, Cookiebot, Quantcast, TrustArc, Didomi) and unlocks frozen page scrollbars immediately.
  • Clean Search Results & 1-Click Element Zapper: Filters out sponsored clutter and low-quality AI content-farm spam on Google, Bing, and DuckDuckGo. Includes a 1-Click Element Hider ("Hide Element") and a 5-Minute Broken-Page Escape Hatch ("Pause 5m" or Alt+Shift+S).
  • Real-Time Scam & Fake Online Shop Detector: Protects your wallet while shopping online by heuristically flagging suspicious counterfeit stores, typosquatted checkouts, and fake countdown timers before you enter payment details.
  • Built-In Tab & RAM Tamer (Memory Optimizer): Automatically snoozes idle background tabs (Alt+Shift+Z) while keeping pinned tabs, active audio, and video calls untouched—plus automatic tab session snapshots.

OUR IRONCLAD PRIVACY & SECURITY GUARANTEE
* 100% On-Device Processing: Your browsing history, search queries, and page content never leave your device.
* Zero Telemetry & Zero "Acceptable Ads": We never collect, log, or sell browsing data, and we refuse payments from ad networks to whitelist their ads.
* Cross-Device Pro Protection: A single SWEEPR Deepblock Pro subscription (starting with our £1.99 1st-month intro offer at https://sweeprdeepblock.com) unlocks full protection across up to 4 devices via instant QR pairing.
