Protects against phishing, IP loggers, fake downloads & browser scams

Features & Capabilities

🛡️ LinkSentry — Your Invisible Bodyguard While Browsing

LinkSentry automatically protects you from phishing, IP trackers, fake downloads, browser lockers, and fake shops — before you even notice.

━━━━━━━━━━━━━━━━━━━━━━

WHY LINKSENTRY?

Every day, millions of people fall victim to online scams. Scammers are getting more sophisticated — fake websites look identical to real ones, IP loggers hide in harmless-looking links, and fake downloads disguise themselves as popular software.

LinkSentry detects these threats and blocks them at the network level — before your data is ever sent.

━━━━━━━━━━━━━━━━━━━━━━

FREE FEATURES

🔒 Phishing Protection Automatically blocks 157,000+ known scam sites from 4 daily-updated feeds. Sites are blocked at network level — they never even load.

📍 IP Logger Detection (UNIQUE!) Detects 70+ known IP tracking services like Grabify, IPLogger, and more. When someone sends you a tracking link, LinkSentry blocks it before your IP address, location, or device data is ever transmitted.

⌨️ Typosquatting Warnings Detects when you land on a fake domain that looks similar to a known website (e.g., paypa1.com instead of paypal.com).

💾 Download Protection Pauses suspicious downloads (.exe, .msi, .dmg) from unknown or very new domains and warns you before you open them.

🔒 Browser Locker Protection Prevents websites from freezing your browser with fake virus warnings designed to trick you into calling a scam hotline.

⚙️ Protocol Blocker Blocks 45 dangerous protocols (ms-settings, steam, discord, etc.) that try to launch programs on your computer.

🔗 Tab Protection Automatically prevents websites from manipulating your other open tabs (reverse tabnabbing).

🔔 Notification Blocker Blocks fake captcha tricks that cause browser notification spam on your desktop.

📋 Clipboard Protection Blocks automatic clipboard access that wasn't initiated by you.

🏪 Fake Shop Detection Analyzes online shops for suspicious signals: new domain, missing legal pages, crypto-only payments, extreme discounts.

🔒 Form Protection Warns you when you enter passwords or credit card data on suspicious sites.

🌐 WebRTC Protection Prevents suspicious sites from reading your real IP address via WebRTC — even if you're using a VPN.

🖱️ Right-Click Scanning Right-click any link, then "Check with LinkSentry" — instantly see if it's safe without opening it.

📊 Dashboard Clean dashboard shows you how many threats have been blocked.

Is LinkSentry 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.

LinkSentry requires a lot of sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

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