Privacy Features

DurgaShield puts your privacy first. Every privacy feature is designed to minimize your digital footprint without compromising functionality.

Stealth Mode

Anti-fingerprinting protection that makes your browser look like everyone else’s:

WebRTC Blocking — Wraps RTCPeerConnection to filter private IP (192.168., 10., 172.16-31.*) ICE candidates — hides local IPs while allowing STUN/TURN relay connections
Canvas Fingerprinting Protection — getImageData passes through clean data; noise added only at toDataURL() / toBlob() output where fingerprinters read the final rendering
Referrer Hiding — Injects <meta name="referrer" content="no-referrer"> to prevent referrer leakage
Hide Automation — Overrides navigator.webdriver to return undefined
Cookie Self-Destruction — Removes non-session cookies older than 1 hour from non-whitelisted domains every 30 minutes
Opt-in: Disabled by default; enable via Stealth Mode switch in popup

Advanced tracking protection inspired by Ghostery:

Navigator Property Spoofing — Randomizes navigator.languages, navigator.hardwareConcurrency, and navigator.deviceMemory
Screen Property Dithering — Adds ±1px noise to screen.width/screen.height; randomizes colorDepth between 24 and 32
Tracking Storage Removal — Clears 50+ tracking keys from localStorage, sessionStorage, and cookies including GA (_ga, _gid), Facebook (_fbp), HubSpot, Intercom, Hotjar, Mixpanel, Amplitude, Segment, FullStory
Opt-in: Disabled by default to avoid breaking site functionality

Blocks known CDN-based tracking domains used for cross-site user identification.

Serves local copies of popular JavaScript libraries instead of fetching them from CDNs:

Bundled libraries: jQuery 3.6.0 / 3.7.1, AngularJS 1.8.3, Modernizr 2.8.3, Bootstrap 4.6.2 / 5.3.3, D3 7.9.0, FontAwesome 6.5.0, Lodash 4.17.21, Moment 2.29.4, React 18.2.0, Vue 3.4.0 (17 files total)
22 DNR redirect rules covering 5 major CDN networks (Google Hosted Libraries, CDNJS, jQuery CDN, jsDelivr, Bootstrap CDN)
Works out of the box — no configuration needed

Auto-dismisses cookie consent banners from all major CMPs:

Supported platforms: OneTrust, Cookiebot, Quantcast, TrustArc, Didomi, Usercentrics, and custom implementations
Preference for rejection: Automatically clicks “Reject All”, “Decline”, “Deny”, or equivalent opt-out buttons
Fallback to dismiss: If no reject option exists, accepts and hides the banner
50+ selectors: Matches common cookie banner selectors and button text patterns

Isolates social media activity using Firefox’s Contextual Identities API:

Container isolation: Facebook, Instagram, Messenger, WhatsApp open in a dedicated “Social Media” container
Cookie isolation: Social media cookies stored only in the container — not accessible from normal browsing tabs
Smart redirect: Navigating to social media from a regular tab automatically redirects to the container
Container indicator: Blue bar at top of isolated pages
Embed blocking: Facebook Like/Share buttons, comments, tracking pixels removed from non-Facebook pages

Strips EXIF data (GPS coordinates, camera model, date/time) from uploaded JPEG images automatically.

Messenger: Hides “Seen by” indicators, read receipts, and typing status
Instagram DM: Suppresses seen indicators and typing indicators in Direct Messages
Active status: Hides “Active Now” / “Active Xm ago” indicators on both platforms
Opt-in: Disabled by default

Annotates Google, Bing, and DuckDuckGo search results with SAFE/RISK badges based on domain trust data.

Strips 200+ tracking parameters from clicked links including fbclid, gclid, utm_*, _ga, _hsenc, ref, si, sk, mtm_*, and more.

AudioContext: Adds random noise (±1 unit, ±0.5 dB) to analyser node outputs
WebGL: Replaces renderer/vendor strings with generic “DurgaShield” prefixes; blocks debug extension info

Heuristic learning: Scans third-party domains on every page and reports them to the background
Cross-site tracking detection: When a third-party domain is observed on 3+ different sites, it’s automatically blocked
Tracker map: Stores domain → [sites...] for full transparency
Popup panel: Shows all detected trackers, sites seen on, and unblock button
