v1.3.7

• Massive Privacy Engine Update: Rebuilt the core tracking protection database using the latest AdGuard and EasyPrivacy filters. We are now blocking over 173,000+ unique tracking and advertising domains.
• Enhanced Cookie Protection: Improved blocking of cross-site trackers and data-collection beacons to keep your personal data private.
• Major Performance Optimization: We’ve re-engineered our ruleset architecture, reducing the rules file size by 2.5x.
• Lighter Footprint: The extension now consumes significantly less disk space and memory while providing even more aggressive protection.
• Faster Loading: Optimized JSON structure ensures near-instant rule indexing by the browser, making your web surfing smoother than ever.

v1.3.6

• Aggressive screen resolution spoofing was causing errors on some sites, even when it was turned off. We’ve replaced it with a lighter method, and now all sites load without errors.

v1.3.5

• Added translations: Spanish, French, German, Russian
• Fixed browser language spoofing — navigator.languages now spoofs correctly
• Fixed mismatch between the number of checks shown on the extension badge vs. the Info tab
• Optimized code for lower load and faster rendering on heavy pages
• Improved time spoofing — fixed an issue where spoofed values could reset to the real ones after reopening the extension popup

v1.2.4

• Added font fingerprint spoofing — a consistent fake profile is used per session.

v1.1.4

User-Agent Spoofing Improvements:

• Requests using the User-Agent string now return fully spoofed values in all cases.

New iframe-based spoofing methods added:

• navigator.userAgent is now spoofed via a sandboxed iframe, blocking external scripts from accessing or modifying the real navigator object.
• navigator.appVersion now uses the same iframe isolation technique to return spoofed values reliably.
