About this extension
PrivacyShield Pro is a fast, lightweight privacy extension designed to give you a cleaner, safer, and more private browsing experience on Firefox.

The extension blocks intrusive advertisements and common third-party tracking requests before they load, helping pages load faster while reducing unnecessary network activity and data exposure. By stopping ads and trackers at the network level, PrivacyShield Pro minimizes clutter, improves performance, and enhances online privacy without breaking websites.

🚫 Ad & Tracker Blocking

PrivacyShield Pro uses Firefox’s modern declarativeNetRequest API to block known advertising networks, tracking scripts, and tracking pixels efficiently and securely. This approach avoids heavy background processing and ensures compatibility with Firefox’s security and performance guidelines.

🛡️ Fingerprinting Resistance

To reduce passive tracking, the extension applies lightweight fingerprinting resistance techniques, including:

-Canvas output normalization
-WebGL parameter standardization
-Reduction of high-entropy browser signals

These techniques help limit fingerprint-based tracking while maintaining website compatibility and stability.

⚡ Performance-Focused Design
PrivacyShield Pro is built to be fast and efficient:

-No continuous background scanning
-No injected remote scripts
-No unnecessary permissions
-Minimal memory and CPU usage

🔐 Local-Only Processing

-All blocking and protection logic runs entirely inside your browser.
-No user data is collected, stored, or transmitted.
-There is no telemetry, analytics, profiling, or tracking of any kind.

🌐 Transparent & Firefox-Compliant

-Fully compliant with Mozilla Add-ons policies
-Uses approved Firefox WebExtension APIs
-No obfuscated or dynamically generated code
-Open, readable source files for review

PrivacyShield Pro is ideal for users who want strong privacy protection, cleaner pages, and better performance—without sacrificing control or trust.
Developer comments
PrivacyShield Pro is a privacy-focused Firefox extension designed to block advertisements and common third-party trackers using Firefox’s approved WebExtension APIs.

The extension uses the declarativeNetRequest API for network-level blocking and content scripts for cosmetic filtering and lightweight fingerprinting resistance. All logic runs locally in the user’s browser. No user data is collected, stored, transmitted, or shared.

The extension does not use:

-Remote or dynamically loaded code
-Obfuscated or minified JavaScript
-External libraries or frameworks
-Telemetry, analytics, or data collection
-Background request interception using webRequest

All source files included in the ZIP are human-readable and represent the complete extension as reviewed.

The fingerprinting resistance features apply conservative normalization techniques (such as canvas and WebGL value standardization) intended to reduce passive tracking while maintaining website compatibility.
