  • Latest version

    Version 4.8.0

    Released Aug 8, 2026 - 694.12 KB
    Works with firefox 113.0 and later, android 120.0 and later
    • Added opt-in privacy-preserving technical analytics for the Firefox build, disabled by default.
    • Added Firefox built-in technicalAndInteraction consent integration on supported Firefox versions, with the existing in-extension opt-in used as a fallback on older supported versions.
    • Added daily aggregated feature-use counters and a seven-day local telemetry queue.
    • Added privacy-safe error fingerprints for DNR, permission, license, rule, Focus Session, background worker, popup, and Options failures.
    • Added a versioned POST /api/telemetry client contract with batch delivery, timeout handling, retention, and exponential backoff.
    • Added a localized Privacy & Technical Data section to every supported locale.
    • Added telemetry delivery state to the privacy-safe Diagnostic Report.
    • No browsing history, blocked website addresses, rule addresses, redirect URLs, email, license key, passwords, raw error messages, stack traces, or persistent telemetry identifier are collected by the telemetry client.
    • No telemetry data is stored before explicit consent. Disabling telemetry clears all pending telemetry buckets and delivery state immediately.
    • Added coarse page-level reporting for uncaught errors and unhandled promise rejections without transmitting messages, filenames, URLs, or stack traces.
    • Reused the existing daily license alarm for telemetry delivery instead of adding another recurring wake-up.
    • Added dependency-free tests for consent, data minimization, aggregation, retention, delivery backoff, UI behavior, localization, and the telemetry request contract.

    Version 4.7.1

    Released Aug 7, 2026 - 666.53 KB
    Works with firefox 113.0 and later, android 120.0 and later
    • Fixed Illegal invocation when clearing diagnostic history by preserving the native confirmation function context.
    • Restored reliable detection of revoked host permissions without bringing back per-tab activation checks.

    • Added a Pro Diagnostic Report to the Options page with generate, copy, JSON export, and history clearing actions.
    • Added a capped local buffer for structured diagnostic events collected only while Debug Mode is enabled.
    • Added live report data for extension and browser versions, access state, settings, rule counts, DNR integrity, host permissions, Focus Session, and license verification.
    • Redacted URLs, domains, email addresses, license keys, tokens, passwords, and other sensitive values before diagnostic data is stored or exported.
    • Added DNR inspection without modifying browser rules and recorded only meaningful DNR changes or failures.
    • Stopped checking host permissions on every tab activation and kept checks on install, update, startup, and permission removal events.
    • Added localized Diagnostics interface strings for every supported locale.
    • Added dependency-free tests for privacy filtering, event buffering, report formatting, UI actions, and DNR inspection.

    • Opened the shared Rule Pack schedule editor above the existing Rule Packs modal instead of behind it.
    • Closed and removed an unfinished nested schedule editor when the Rule Packs dialog is cancelled or closed.
    • Applied the default weekday schedule when scheduling is enabled without opening the editor, preventing newly imported rules from receiving null schedules.
    • Kept Escape scoped to the nested schedule editor before allowing it to close the Rule Packs dialog.
    • Added regression tests for nested modal hosting, cleanup, and default shared schedule retrieval.

  • Version 4.3.1

    Released Aug 5, 2026 - 582.14 KB
    Works with firefox 113.0 and later, android 120.0 and later
    • Reduced RulesManager to current rule storage, validation, duplicate detection, and conflict checks.
    • Moved legacy rule migrations into a dedicated service with explicit storage dependencies.
    • Moved rule activation decisions and DNR rule construction into isolated, testable modules without changing matching or schedule behavior.
    • Moved rule intent routing out of the service worker into a small tested command router.
    • Added a dependency-free npm run check command for tests, syntax checks, JSON validation, manifest references, version consistency, and referenced English localization keys.
    • Expanded the permanent test suite to cover migration safety, rule activation, DNR construction, intent routing, validation semantics, and service-worker module loading.
    • Protected existing local rules from being overwritten by stale synchronized rules when the migration flag is missing.
    • Ensured migrated rules and the device migration flag are written together when copying legacy synchronized rules.
    • Kept failed storage migrations retryable by not marking them as completed.

  • Version 4.0.0

    Released Jul 15, 2026 - 577.4 KB
    Works with firefox 113.0 and later, android 120.0 and later
    • Storage Migration: Rules database has been migrated from browser.storage.sync to browser.storage.local. Automatic background synchronization of rules across different devices is no longer supported. General extension settings (theme, toggles) are still synchronized via sync storage.
    • Unlimited capacity for power users (up to 10MB+ storage via local API), completely bypassing Firefox's legacy QUOTA_BYTES_PER_ITEM errors.
    • One-time local migration handler to safely move existing rules from sync to local storage on the first launch of v4.0.0.
    • Fixed browser extensions crashing or throwing unhandled database exceptions when saving massive rule lists.

  • Version 3.10.10

    Released Jul 13, 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 Jul 9, 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 Jul 8, 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 Jul 7, 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.
