"Troubleshooting Trezor Bridge: Common Issues and How to Fix Them"

Trezor Bridge is a small utility that performs a big job — enabling secure communication between your Trezor hardware wallet and your browser. While it generally runs smoothly, some users may encounter hiccups. In this post, we’ll walk you through common Trezor Bridge issues and how to solve them quickly.

Quick Refresher: What Is Trezor Bridge?

Trezor Bridge is a background process that connects your browser (like Chrome or Firefox) to your Trezor hardware wallet. It’s especially useful for the Trezor Suite web app or browser-based third-party integrations.

If your browser isn’t recognizing your Trezor device, chances are the issue is with Trezor Bridge.

Common Issues with Trezor Bridge

1. Browser Not Detecting the Device

Symptoms: You plug in your Trezor, open Trezor Suite Web, and see an error like “No device detected.”

Solutions:

  • Make sure Trezor Bridge is installed.
  • Restart your browser after installing Bridge.
  • Try switching USB ports or using the original cable.
  • Disable other extensions that might conflict with USB communication.

2. Trezor Bridge Not Running

Symptoms: The Trezor website keeps asking you to install Bridge even after you've already done it.

Solutions:

  • Check if the process is running in the background.
  • On Windows: Look in Task Manager for trezord.exe
  • On macOS/Linux: Run ps in Terminal to see if it’s active.
  • Reinstall Bridge if it’s not running.

3. Outdated Version

Symptoms: Unexpected errors or failure to connect to your wallet.

Solutions:

  • Visit https://suite.trezor.io/web to check if an update is required.
  • Reinstall the latest version of Bridge from the official site.

Tips to Avoid Bridge Problems

  • Always install from official sources
  • Avoid browser add-ons that interfere with USB
  • Use Trezor Suite Desktop if Bridge continues to misbehave — it doesn’t require Bridge at all

When You Don’t Need Trezor Bridge

If you’ve moved to the Trezor Suite Desktop, you can safely uninstall Bridge. The desktop app manages communication directly with your hardware wallet and offers more features like portfolio tracking, in-app exchanges, and better UX.

Final Advice: Keep Everything Updated

Trezor constantly improves both its firmware and support software like Bridge. Always check for updates before you start a session, especially after OS upgrades or browser updates.
