    2257 Compliance Detection
    • New detector module: js/detectors/2257-compliance-detector.js
    • Detects 18 U.S.C. § 2257 compliance statements in anchor tags to identify adult content sites
    • Rule-based matching with 6 detection patterns:
      • compliance_statement: 2257 + compliance + statement
      • custodian_records: 2257 + custodian + records
      • exempt_exemption: 2257 + exempt/exemption (union)
      • usc_reference: 18 + USC/U.S.C. (union) + 2257
      • record_keeping: 2257 + record-keeping/record keeping (union)
      • cfr_reference: 28 + CFR/C.F.R. (union) + 75
    • Only evaluates same-domain links (link href hostname must match current page hostname) to eliminate cross-domain false positives
    • Page-level whitelist skips scanning entirely on known safe domains: .gov, .edu, .law, wikipedia.org, justia.com, aclu.org, oyez.org, eff.org, duckduckgo.com, google.com, bing.com, yahoo.com, chanrobles.com, laws-info.com, law.com
    • Regex-based skip for US state government domains matching *.XX.us pattern (e.g. courts.state.ny.us)
    • Skips file: protocol pages
    • MutationObserver with 250ms debounce for dynamic content detection (SPAs, infinite scroll)
    • Runs indefinitely — never disconnects the observer
    • Safety gate using data-2257-checked attribute to prevent re-checking links
    • Logging via console.debug() for verbose browser output
    • Signal integration: New ICRA:2257 signal maps to the Sexual/Nudity category
    • Block reason: "Sexual/Nudity (2257 Compliance)" displayed in block overlay
    • Block overlay "Why:" section: When a block is triggered by the 2257 detector, the overlay now shows the matching link text and URL below the Reason line to aid in diagnosis

  • Version 1.2.0

    Released Nov 27, 2025 - 152.78 KB
    Works with firefox 109.0 and later
    Major New Feature: Safe Request Mode We have introduced "Safe Request Mode," which automatically enforces server-side safety filters for popular search engines and content platforms. This works alongside our existing on-page filtering to provide multi-layered protection.

    Search Engines: Enforces "SafeSearch" or "Strict Mode" for Google, Bing, Yahoo, and DuckDuckGo.
    YouTube: Enforces Restricted Mode (Strict or Moderate).
    Tumblr Integration (New in 1.2.0): Seamlessly filters mature content from Tumblr feeds without breaking the page layout. This includes:
    Filtering initial page content.
    Intercepting background API requests (infinite scroll).
    Removing posts labeled as "Potentially mature," "Adult," or "Explicit."
    New Feature: Self-Lock Mode Designed for voluntary content restriction, Self-Lock allows users to lock the filter settings for a set duration.

    Flexible Timers: Lock for 1 hour, 24 hours, 1 week, or a custom duration.
    Anti-Tamper: Prevents disabling the extension or changing settings while active.
    Strict Enforcement: Optionally enforces Safe Request Mode and overrides allow-lists during the lock period.
    Recovery: Includes a secure recovery code system and a "cool-down" unlock mechanism to prevent impulsive decisions.
    Enhancements:

    Settings UI: Completely redesigned settings page with tabbed navigation (General, Self-Lock, Security, Safe Request Mode).
    Security: Separate passphrases for Admin settings and Self-Lock mode.
    Performance: Optimized content detection scripts for faster page loads.
