🛡️ JUSTBLOCK - BLOCK ADS. BROWSE SAFER. More than an ad blocker. JustBlock brings together free ad blocking, popup protection, tracker filtering and practical privacy controls to make everyday browsing cleaner, quieter and safer. Install JustBlock and start protecting your browser automatically. No account required. No complicated setup. Core protection stays free. Want more? Upgrade to Max Clean Pro for scam popup warnings, automatic page cleanup, Focus Mode and privacy tools. ✅ FREE BROWSER PROTECTION 🚫 AD BLOCKER & POPUP BLOCKER Enjoy browsing with fewer unwanted interruptions. • Block many intrusive advertisements using built-in filtering rules. • Stop unwanted automatic popups and pop-unders. • Reduce interruptions from known popup advertising networks. • Allow recently user-initiated windows to help keep logins and payments working. • Pause protection or trust individual websites whenever needed. Protection works automatically on supported websites, although no blocker catches every ad or popup. 🔒 TRACKER & CRYPTOMINER PROTECTION Reduce selected tracking requests and known cryptomining resources. • Block listed email-tracking pixels. • Reduce Facebook and other supported tracking requests. • Block known cryptomining scripts and domains. • Help reduce unnecessary background requests. Filtering uses bundled rules and does not detect every tracker or online threat. 🔗 LINK CLEANUP & PRIVACY CONTROLS Keep more control over your browsing. • Remove common tracking parameters such as utm, fbclid and gclid. • Clean your current webpage URL with one click. • Add trusted websites to your allowlist. • Pause or resume protection whenever needed. • View recent protection activity stored locally. • Enable optional filtering lists for selected scam domains, clickbait, search redirects and other unwanted content. Link cleanup is manual. Optional filtering lists are off until enabled. ⭐ MAX CLEAN PRO — TAKE CONTROL OF YOUR BROWSER Go beyond traditional ad blocking with additional tools for a cleaner, more focused and private browsing experience. 🚨 SCAM POPUP WARNINGS Get optional warnings about certain suspicious popups that imitate virus alerts or fake technical-support messages. • Detect selected combinations of suspicious warning signs. • Identify certain messages pressuring you to call technical support. • Review a warning before deciding whether to hide the suspicious element. • Enable or disable this feature whenever you prefer. Detection runs locally and is based on visible content patterns. It is not comprehensive phishing detection or antivirus protection. ✨ AUTOMATIC PAGE CLEANUP Remove more distractions from supported webpages. • Hide matching cookie notices and overlays. • Reduce newsletter signup popups. • Hide promotional banners and sticky offers. • Remove floating chat and video panels. • Select unwanted page elements yourself. • Save custom blocks and website preferences. • Undo cleanup or pause individual websites. Hiding cookie notices does not automatically accept or reject cookies. 🎯 FOCUS MODE Make supported websites less distracting. • Timed focus sessions. • Weekly focus schedules. • Reduce selected recommendations and distracting feeds. • Optional controls for Shorts, comments and other supported content. • Focus controls for selected YouTube, LinkedIn and Reddit pages. Stay focused without blocking your entire internet connection. 🔐 PRIVACY MASKS & REDACTED SCREENSHOTS Share what you want others to see. • Manually select sensitive webpage areas. • Cover selected content with privacy masks. • Capture screenshots with selected areas redacted. • Review screenshots before saving. • Manage and remove saved masks. Privacy masks visually conceal selected areas; they do not delete the underlying webpage information or automatically detect sensitive data. 💎 FREE PROTECTION. OPTIONAL PREMIUM TOOLS. JustBlock's core features remain free, including ad blocking, popup protection, tracker filtering, link cleanup, trusted-site controls and optional filtering lists. Max Clean Pro adds page cleanup, Focus Mode, scam popup warnings, privacy masks and screenshot redaction. **Max Clean Pro: $39.99/year** Equivalent to approximately $3.33/month, billed annually with automatic renewal. It is not a monthly subscription. You never need Max Clean Pro to continue using JustBlock's free core protection. 🔒 PRIVACY & TRANSPARENCY Core filtering and Max Clean page cleanup operate locally in your browser. • No account required for free protection. • Browsing history is not uploaded by JustBlock. • Recent activity and cleanup preferences are stored locally. • Subscription services process information needed for billing and premium access. • Webpage contents are not sent to the billing service. ⚠️ IMPORTANT TO KNOW JustBlock is a browser protection extension, not antivirus software. It does not scan downloaded files, remove malware, detect every scam or provide comprehensive phishing protection. Scam popup warnings are optional, pattern-based and may miss threats or produce false positives. Website filtering and page cleanup depend on available rules and website structure. 🚀 INSTALL JUSTBLOCK TODAY Block ads. Stop unwanted popups. Reduce trackers. Browse with fewer interruptions.
