Troubleshooting Trezor Bridge Issues

Browser Not Detecting Device

  • Confirm Trezor Bridge is running in background
  • Visit ➡️ http://127.0.0.1:21325/ — if this page opens, Bridge is active
  • Reconnect your USB cable or try a new port
  • Restart your browser or computer

Installation Blocked on macOS

If macOS security prevents installation:

  • Go to System Settings > Security & Privacy
  • Click “Allow” under the message for Trezor Bridge
  • Reinstall the application

Bridge Not Working on Linux

  • Ensure udev rules are installed
  • Use root access if needed during installation
  • Reboot the system for full driver recognition

How Trezor Bridge Compares to Browser Extensions

Trezor used to offer Chrome and Firefox extensions, but these were deprecated due to:

  • Security vulnerabilities
  • Limited browser support
  • Maintenance challenges

Trezor Bridge replaces extensions with:

  • A more stable interface
  • Reduced reliance on browser architecture
  • No need for permissions that extensions require

Which Browsers Work with Trezor Bridge?

Bridge supports most modern browsers:

  • ✅ Google Chrome
  • ✅ Mozilla Firefox
  • ✅ Microsoft Edge

⚠️ Safari is not supported due to its restrictions on USB device communication.

Does Trezor Suite Desktop Require Bridge?

No. If you're using Trezor Suite Desktop, Bridge is not needed because the desktop app includes its own communication layer.

However, for browser-based operations, Bridge is mandatory for consistent device detection and functionality.

Best Practices for Trezor Bridge Users

  • Always download from Trezor.io/start
  • Keep your system and browser updated
  • Reboot after installation or updates
  • Check that only one communication method is active (disable WebUSB if using Bridge)
  • Occasionally check for Bridge updates from the official site
