DBlocker

User-controlled blocker for intrusive popups, redirects, click overlays, outbound navigation traps, and unwanted embedded frames.

DBlocker is a powerful, user-controlled browser extension built to eliminate aggressive popups, pop-unders, auto-redirect traps, invisible click overlays, and malicious ad iframes on video streaming, reading, and media websites. Designed to be lightweight, precise, and privacy-first, DBlocker puts complete control back into your hands, ensuring a clean and seamless browsing experience without disruptive hijackings. KEY FEATURES: • Comprehensive Popup & Popunder Blocker: Neutralizes aggressive new windows, tab-unders, and automated window.open triggers whenever you click on the page. • Click Overlay Neutralizer: Automatically detects and removes invisible, full-screen overlay layers designed to hijack your first click to external ads. • Programmatic Redirect Defense (Anti-Redirect): Prevents hostile websites from forcing page redirects via Navigation APIs, Location hooks, Meta refresh tags, or cross-origin history manipulation. • Smart Video Player Protection: Intelligently distinguishes ad iframes from legitimate video players. Keeps video player frames clean and intact so your playback is never broken. • TLD-Independent Site Key Protection: Remembers your protection settings based on the website's brand identity rather than top-level domains. Whether a site migrates from .com to .xyz, .net, or .cc, your protection remains seamless. • Granular Allowlist Controls: Fine-grained permissions separated by type (iframe, popup, redirect, external-link). Whitelisting a trusted embedded player will never grant it popup or redirect privileges. • Clean & Intuitive Interface: Fast 3-tab popup (Blocked / Allowed / Sites) with real-time blocked counter badges, plus a full Options Dashboard for configuration backup and restore via JSON. PRIVACY & SECURITY COMMITMENT: • 100% Local Execution: All detection and blocking logic runs directly on your device. • Zero Data Collection: DBlocker does not track browsing history, does not collect personal data, and has no remote telemetry. • Ad-Free & Clean: Never injects third-party ads, affiliate links, or sponsored code. HOW TO USE: 1. Navigate to the website you want to protect (e.g., video streaming or reading site). 2. Click the DBlocker icon on your browser toolbar. 3. Toggle the protection switch to ON.
