    Anti-Fingerprinting
    • Override Temporal.Now APIs (timeZoneId, plainDateTimeISO, plainDateISO, plainTimeISO, zonedDateTimeISO)
    • Fix timezone offset hash split — all Date APIs now derive from a single resolution path per engine
    • Use browser's native IANA tzdata via Intl.DateTimeFormat instead of custom offset arithmetic
    • Fix Date constructor epoch for historical sub-minute LMT offsets
    • Harden prototype detection resistance (method shorthand wrapping, stack trace cleanup, synchronous iframe patching)
    • Strip console output from production builds (fixes extension name leak)

    Internal
    • Modularize injected script into 15 ES modules (still bundled as single IIFE)
    • Expanded property-based test suite for fingerprint consistency

    Other
    • Lower minimum Firefox version to 140
    • Add Waterfox build script and Chrome Web Store assets

  • Version 1.11.0

    Released 11 Mar 2026 - 121.14 kB
    Works with firefox 142.0 and later, android 142.0 and later
    v1.11.0

    New Features
    • VPN Region Sync — New "Sync with VPN" toggle that detects your public IP, geolocates your VPN exit region, and sets your spoofed location to match. One click, no manual coordinates needed.
    • Re-sync — After syncing, a Re-sync button lets you update your spoofed location if you switch VPN servers.
    • Info tooltip — ⓘ icon next to the VPN sync toggle explains that it's a one-time sync (not auto-updating) and that Re-sync is needed after changing VPN servers.
    • Clear location — New × button on the current location display to quickly clear your spoofed location.

    Improvements
    • Settings deferral hardening — Geolocation and permissions queries are now deferred until settings arrive from the background script, preventing real location leaks on slow startups.

    Documentation
    • Rewrote the Development section in README with a clear "two terminals" workflow and a scripts reference table.
    • Added package:source to the scripts table.
    • Updated Android testing instructions.
    • Updated Privacy Policy with VPN sync data disclosure (ipify + FreeIPAPI).

    Housekeeping
    • Removed unused build:ext / zip script (redundant with package).

  • Version 1.10.0

    Released 10 Mar 2026 - 118.07 kB
    Works with firefox 142.0 and later, android 142.0 and later
    v1.10.0

    Bug Fixes
    • Fixed false orange "!" badge appearing on nearly every page load due to a race condition between the background script and content script initialization
    • Badge now retries injection checks with backoff (500ms, 1s, 2s) instead of failing immediately
    • Badge automatically recovers to green "✓" when the content script confirms it's active
    • Popup injection warning now uses a live PING check instead of reading potentially stale badge text, reducing false warnings on SPA navigations (e.g., YouTube)

  • Version 1.5.0

    Released 8 Mar 2026 - 306.76 kB
    Works with firefox 142.0 and later
    v1.5.0
    New: Permissions API Spoofing
    - navigator.permissions.query() now returns "granted" for geolocation when spoofing is active, closing a fingerprinting gap where websites could detect spoofed location by checking the permission state.
    - Non-geolocation permission queries and all queries when spoofing is disabled pass through to the browser normally.
    - The spoofed PermissionStatus object matches the real browser API surface (read-only state, EventTarget support).
    - No additional browser permissions required.

    Fixes
    - Fixed popup Details view not rendering line breaks in the Overridden APIs and other detail sections.
    - Package script now auto-formats manifest.json after build.
