About

TabSanity prevents duplicate tabs by automatically switching to existing ones, keeping your browser organized and improving
  performance.

  🚀 Key Features:
  • Automatically detects and prevents duplicate tabs
  • Multiple URL matching modes (exact, ignore query params, ignore hash)
  • Customizable deny list with regex patterns for sites where you want multiple tabs
  • Real-time statistics tracking duplicates prevented
  • Optional notification badge counter
  • Import/export settings for backup

🎯 Perfect for:
  • Heavy browser users with many tabs
  • Developers working with multiple windows
  • People like me that keep opening the same tab over and over

  ⚙️ Smart Matching:
  Choose how URLs are compared - exact matching, or ignore query parameters/hash fragments for flexible duplicate detection.

  🛡️ Privacy Focused:
  Only accesses tab information to prevent duplicates. No browsing history is stored or transmitted.
