  • Latest version

    Version 3.10.10

    Released 13 Jul 2026 - 576.6 kB
    Works with firefox 113.0 and later, android 120.0 and later
    • Service worker alarm resets on mobile: Fixed a critical issue in Firefox Mobile (GeckoView) where background alarms were repeatedly reset to their initial delay upon every service worker wake-up. Integrated an asynchronous browser.alarms.get verification routine to ensure persistent, non-overlapping background scheduling.
    • Fragile background delays: Eliminated legacy setTimeout structures inside the startup and permission handlers. DNR integrity checks and state hydration now execute via solid, synchronous promise chains (await), preventing the browser from prematurely killing the background script during active processing.
    • Tab switching performance: Optimized the onActivated tab listener to strictly handle authorization states without re-triggering heavy storage queries. This completely removes CPU overhead and battery drain during rapid tab switching on mobile devices.
    • Deterministic lifecycle execution: Re-architected the checkAndRequestPermissions state lock using a robust try...finally block, ensuring the permission flag state resets instantly and reliably regardless of execution errors.

  • Version 3.10.7

    Released 9 Jul 2026 - 575.92 kB
    Works with firefox 113.0 and later, android 120.0 and later
    • Dynamic focus session visibility: Enhanced the popup UX by dynamically toggling the focus session section based on the user's rules list. The focus section is now hidden by default if no blocking rules exist, keeping the interface clean and clutter-free for fresh installs.
    • Reactive UI state handling: Integrated visibility logic directly into the central updateStatus routine. The focus control panel now automatically reveals itself the moment a rule is added (via the popup or the "Block this site" button) and seamlessly hides if all rules are deleted.
    • Layout shift prevention: Added the hidden utility class directly to the HTML structure to prevent any visual flickering or layout shifts during the popup's initialization phase.

  • Version 3.10.6

    Released 8 Jul 2026 - 644.58 kB
    Works with firefox 113.0 and later, android 120.0 and later
    • Batch tab closure optimization: Replaced individual, loop-bound chrome.tabs.query operations with a unified batch function. The extension now queries open tabs exactly once and checks them against all active patterns simultaneously, reducing browser API overhead and fixing noticeable delays during focus session activation.
    • Centralized DNR synchronization: Removed the redundant syncDnrRules method from RulesManager. The service worker is now established as the single source of truth for all declarativeNetRequest updates, preventing double-syncing resource consumption when rules are saved.
    • Streamlined rule saving: Refactored popup and options actions to strictly handle data storage and trigger a single background reload event, ensuring smooth, non-blocking UI transitions.

  • Version 3.10.5

    Released 7 Jul 2026 - 644.39 kB
    Works with firefox 113.0 and later, android 120.0 and later
    • Restored redirect functionality: Fixed a critical bug where normalizePathSegment incorrectly applied encodeURIComponent to the entire redirect URL, transforming https:// into https%3A%2F%2F and causing new URL() and location.replace() to fail in redirect.js.
    • Flexible keyword blocking: Separated the normalization logic for path segments/domains from full redirect URLs. Keyword-based matching (e.g., entering tube to block youtube.com) remains fully functional.
    • Parameter security: Improved validation for incoming from and to query parameters inside redirect.js to prevent crashes when handling malformed strings.
