Trezor Bridge Not Working? Fix It Fast

Trezor Bridge allows your browser to communicate securely with your Trezor hardware wallet. If it stops working, your device may not be recognized, preventing access to your wallet. These steps will help you resolve the issue quickly.

1. Restart Your Computer and Browser

This simple step often clears out temporary connection errors.

• Disconnect your Trezor device
• Restart your computer
• Open your browser again
• Reconnect your Trezor

2. Confirm Trezor Bridge Is Installed

Make sure you downloaded Trezor Bridge from the official site:

• Visit trezor.io/bridge
• Re-download and reinstall the version for your operating system
• Restart your computer after installation

3. Verify That Bridge Is Running

Check if the Bridge process is running in the background:

• Windows: Look in the Task Manager for "trezord" or "Trezor Bridge"
• macOS: Use Activity Monitor to check for the process
• Linux: Use your system monitor or terminal

If it is not running, start it manually or reinstall it.

4. Use a Different USB Port or Cable

• Use the original Trezor USB cable if possible
• Avoid USB hubs or splitters
• Try different USB ports on your computer

5. Check Your Browser

Trezor Bridge works best with Chromium-based browsers like Chrome, Brave, or Edge. If your browser is outdated or incompatible:

• Update your browser to the latest version
• Try another browser (Chrome or Firefox are recommended)
• Clear your browser cache and cookies

6. Disable Conflicting Extensions

Browser extensions can sometimes interfere with Trezor Bridge.

• Disable extensions like ad blockers, privacy tools, or antivirus plugins
• Try using a private/incognito window

7. Disable or Configure Antivirus/Firewall

Some antivirus software blocks USB or background communication.

• Temporarily disable antivirus and firewall to test if they are causing the issue
• Add Trezor Bridge to your antivirus’s trusted list

8. Use the Trezor Suite Desktop App

Trezor Suite desktop does not require Trezor Bridge and often provides a more reliable connection.

• Download it from
• Install it and connect your Trezor via USB
• This bypasses browser and Bridge-related problems entirely

9. Uninstall and Reinstall Bridge

If Bridge is still not working:

• Uninstall it completely from your computer
• Reboot your computer
• Reinstall the latest version from the official Trezor website
• Restart again and test the connection
