Trezor Bridge Not Working? Fix It Fast

Trezor Bridge is a crucial piece of software that lets your browser communicate securely with your Trezor hardware wallet. But sometimes, it doesn’t work as expected — your device isn’t detected, or the connection fails. Don’t worry: most issues are quick and easy to fix.

This guide will walk you through why Trezor Bridge might not be working and how to solve the problem fast, so you can get back to managing your crypto with confidence.

🧩 What Causes Trezor Bridge to Stop Working?

Here are the most common reasons Trezor Bridge might fail:

  • It wasn’t installed correctly
  • Your browser needs a restart
  • Outdated or conflicting browser extensions
  • Multiple wallet apps running at once
  • Outdated firmware or Bridge version
  • Operating system or USB port issues

Let’s troubleshoot step by step.

✅ Quick Fix Checklist

1. Restart Your Browser and Computer

Sometimes, a simple restart solves the problem. After installing or updating Trezor Bridge:

  • Close and reopen your browser
  • If that doesn’t help, restart your computer

2. Check That Bridge Is Installed

Go to:
127.0.0.1:21325/status/

If you see a status page showing Bridge is running, that’s a good sign. If the page doesn’t load, Bridge isn’t running.

Fix: Reinstall Bridge from the official Trezor site at trezor.io/start, and then restart your computer.

3. Try a Different Browser

Trezor Bridge works best with Chrome, Firefox, or Edge. Avoid using unsupported or privacy-hardened browsers unless you're experienced with their configurations.

Switch to a supported browser and retry.

4. Check USB Connection

  • Use the original cable that came with your Trezor
  • Try a different USB port on your computer
  • Avoid using USB hubs or adapters, especially on older machines
  • Make sure the cable supports data transfer (not just charging)

5. Disable Conflicting Browser Extensions

Some extensions — especially ad blockers, privacy tools, or security add-ons — can interfere with Trezor Bridge.

Try this:

  • Open your browser in Incognito/Private mode
  • Disable extensions temporarily
  • Refresh the page and reconnect your Trezor

6. Update Firmware and Bridge

Outdated software is a common cause of connection problems.

  • Make sure your Trezor firmware is up to date using the Trezor Suite desktop app
  • Reinstall the latest Trezor Bridge from the official website
  • Clear your browser cache and try again

7. Make Sure No Other Wallet Apps Are Open

Running Trezor Suite desktop while trying to connect via browser can cause conflicts.

Close any other wallet apps, including Trezor Suite, before using a browser-based wallet that relies on Trezor Bridge.

🧪 Advanced Fixes (If Nothing Else Works)

Check for Background Processes

On Windows/macOS/Linux, make sure Trezor Bridge is running in the background. You can check via:

  • Windows: Task Manager → Look for trezord.exe
  • macOS: Activity Monitor → Look for Trezor-related processes
  • Linux: Use the ps command to verify

If it’s not running, try reinstalling Bridge.

Firewall or Antivirus Conflicts

Firewalls or antivirus software may block Bridge.

  • Temporarily disable them and test again
  • Whitelist Trezor Bridge manually in your firewall settings

Use the Desktop App Instead

If you're still having trouble, the Trezor Suite desktop application is the easiest and most stable option. It doesn’t require Trezor Bridge and connects to your Trezor device directly.

Download it from:
trezor.io/start

🛠️ How to Reinstall Trezor Bridge (Cleanly)

  1. Uninstall Trezor Bridge from your computer
  2. Restart your system
  3. Go to trezor.io/start and download the latest version
  4. Install it, then restart your browser

After reinstalling, plug in your Trezor and visit suite.trezor.io/web to test it.

🔒 Security Tip

Always download Trezor Bridge from the official Trezor website. Never trust third-party download sites or links from unverified sources.

🚀 Final Thoughts

Trezor Bridge not working can be frustrating — especially when you're trying to check balances or move funds quickly. But in most cases, it's just a temporary issue caused by browser settings, software conflicts, or outdated tools.

By following these simple steps, you can get your Trezor device connected and working again in just a few minutes. And if problems persist, you can always switch to the desktop version of Trezor Suite, which doesn’t require Bridge at all.
