Troubleshooting Trezor Bridge Connection

How to fix Trezor connection problems in your browser quickly and safely

Trezor hardware wallets rely on a small background app called Trezor Bridge to communicate with web browsers. If this connection breaks or fails, your Trezor device may not be recognized by Trezor Suite Web or other wallet platforms.

This guide will help you identify and fix Trezor Bridge connection problems across all major systems.

What Is Trezor Bridge?

Trezor Bridge is a communication service that runs in the background on your computer. It allows your browser to securely talk to your Trezor hardware wallet. It is essential when using the web version of Trezor Suite or when connecting Trezor to third-party apps like MetaMask.

If Trezor Bridge is missing, outdated, or blocked, your device may fail to connect or remain undetected.

Common Connection Problems

Here are the most frequent signs that something is wrong with your Trezor Bridge setup:

  • "Trezor Bridge not running" error message
  • The device does not appear in the browser interface
  • Trezor Suite Web remains stuck on "Looking for your device..."
  • Repeated prompts to reconnect the hardware wallet

These are usually caused by issues with installation, browser compatibility, or software conflicts.

Step-by-Step Solutions

1. Check if Trezor Bridge is Installed

Go to your list of installed apps or programs and confirm that Trezor Bridge is present. If it is not, download the latest version from the official Trezor website and install it. After installation, restart your computer to activate the background service.

2. Restart Your Computer

A reboot often fixes temporary communication issues and ensures the Trezor Bridge service starts properly. After restarting, plug in your Trezor and open Trezor Suite Web in your browser.

3. Use a Supported Browser

Trezor Bridge is optimized for modern browsers like Chrome, Firefox, and Edge. Avoid using Safari or Brave, as they may block necessary background scripts or USB access.

If using Brave, disable its ad-blocking and privacy shields for the Trezor website.

4. Disable Browser Extensions

Some browser extensions, such as ad blockers, privacy tools, or MetaMask, may interfere with Trezor Bridge. Temporarily disable all extensions and try again. Once the device is recognized, you can re-enable extensions one at a time to find the culprit.

5. Clear Browser Cache

Old cookies or cached scripts can prevent a clean connection. Clear your browser cache and cookies, close the browser, and try again. This step is especially important after a recent Trezor Bridge update.

6. Confirm Bridge Is Running in Background

Check if the Trezor Bridge service is running:

  • On Windows: Open Task Manager and look for "trezord"
  • On macOS: Use Activity Monitor and search for the same process name

If it's not active, launch the Trezor Bridge application manually or reinstall it.

7. Reinstall Trezor Bridge

If Bridge appears broken or outdated, remove it completely from your system, restart your computer, and install the latest version from the official Trezor site. This step solves most persistent issues.

8. Try Trezor Suite Desktop

The desktop version of Trezor Suite does not rely on Trezor Bridge at all. If you're having browser-related issues, switch to the desktop app for a smoother and more stable experience.

Additional Troubleshooting Tips

  • Use a direct USB connection instead of a USB hub
  • Switch to a different USB port or try a different cable
  • Make sure your cable supports data transfer (not just charging)
  • Allow Trezor Bridge through your firewall or antivirus software
  • If your operating system blocks the application, add it to the trusted list

Still Not Working?

If the issue persists after following these steps:

  • Test your Trezor on a different computer
  • Ensure your browser is fully up to date
  • Contact Trezor Support with details about your OS, browser, and device model

Final Thoughts

Trezor Bridge connection issues are common, but they are usually easy to fix with a few simple checks. Make sure Trezor Bridge is installed, updated, and not blocked by your system or browser. If you're frequently experiencing issues, consider switching to the desktop version of Trezor Suite, which offers the same features without requiring the Bridge.
