But here's what makes it truly different: it doesn't force your hand. No mandatory nags, no hard content locks, no prescribed popups. Reactor simply gives you actionable information and powerful hooks, then gets out of the way. You decide how (or if) to respond to an adblock detection. If you want to detect and react to ad blockers - this extension is for you.

Key Features

• Robust, Future-Proof Detection
  • Combines DOM bait (with per-load randomization), local transparent GIF probes, and worker-based network bait targeting real ad scripts - with smart timing/size analysis to defeat stubs and fake responses.
• Dynamic ACL Integration
  • Optionally add users to a custom Viewing Access Level when blocking is detected (adACL), and switch to a different level when they disable/clear it (clearACL). Perfect for:
  • Showing fallback house ads or affiliate banners to blockers Unlocking premium modules or discounts for compliant users Displaying a timely "Thank you for whitelisting!" offer or subscription nudge
• Flexible Content Reactions (for articles)
  • When blocking is active:
  • Truncate content (at read-more or custom HTML point) + optional append message
  • Redirect to another page/menu item (with optional system message)
  • Page-view counter: allow X views before escalating (e.g., redirect)
  • Expose counter data to custom JS for dynamic UI
• Custom JavaScript Hooks
  • Fire scripts on detection, on clearance, or on status change. Track events in GA4/Matomo, show modals, update UI - whatever fits your site.
• Zero Bloat Philosophy
  • No forced outputs, no unnecessary markup. Reactor runs quietly and only triggers the reactions you define.
