Trezor Bridge Not Working? Fix It Fast
If your Trezor wallet isn't connecting properly to your browser or Trezor Suite, there's a good chance the issue lies with Trezor Bridge. Trezor Bridge is the communication software that connects your Trezor hardware wallet to web browsers and desktop apps. When it fails, your device won’t be recognized, transactions won’t go through, and you’ll likely see an error message saying the device isn’t connected.
Fortunately, fixing Trezor Bridge problems is usually quick. Here's a step-by-step guide to get you back on track.
What Is Trezor Bridge?
Trezor Bridge is a small background application that allows your web browser or desktop interface (like Trezor Suite) to communicate with your Trezor hardware wallet. It's required for most browsers except Chrome with WebUSB support or when using the Trezor Suite desktop app.
If it's not installed or working correctly, the wallet simply won’t function as expected.
Common Signs Trezor Bridge Isn’t Working
- Your Trezor device isn’t detected
- You’re stuck on a “Connect your device” screen
- You see “Trezor Bridge is not running” errors
- Nothing happens when you plug in the wallet
- The browser fails to prompt any interaction
Quick Fixes for Trezor Bridge Issues
1. Check If Trezor Bridge Is Installed and Running
Open your Task Manager (Windows) or Activity Monitor (macOS) and look for a process named trezord. If you don’t see it, the Bridge is not running.
Solution: Reinstall the latest version of Trezor Bridge. Make sure you close all browsers before doing so.
2. Restart Your Computer
It might sound basic, but restarting your system will reset background services and may allow Bridge to start properly. Always try this before diving into deeper troubleshooting.
3. Disable Conflicting Apps or Extensions
Browser extensions, antivirus software, or USB security tools can block communication between the device and Bridge.
Try this:
- Close all browser extensions (especially crypto wallets and security tools)
- Temporarily disable antivirus or firewall software
- Reconnect your Trezor after doing this
4. Try a Different Browser
Trezor Bridge is designed to work best with Firefox and Chrome. If one browser doesn’t detect your device, try the other. Avoid using privacy-focused browsers (like Brave or Tor) for setup unless configured properly.
5. Use Trezor Suite Desktop Instead
Trezor Suite desktop doesn't require Trezor Bridge at all. It communicates directly with the Trezor device. If Bridge is giving you persistent trouble, switching to the desktop app can solve the issue instantly.
6. Update Trezor Firmware and Software
Outdated firmware or Trezor Bridge versions can cause connection failures. Make sure you are using the latest:
- Trezor Bridge software
- Trezor Suite version
- Device firmware
If you can’t update due to the bridge issue, try using another computer just for the update.
7. Replace the USB Cable or Port
A faulty cable or port can mimic software problems. Use the original cable that came with the Trezor device, or try another high-quality USB data cable. Also try different USB ports, preferably direct ones—not hubs.
Advanced Tip: Check Bridge Permissions
If you're technically inclined, ensure that Trezor Bridge has permission to run in the background or that it isn’t being blocked by your system’s privacy settings. On macOS, for example, you may need to allow background items in System Settings.
When to Contact Support
If you've tried all the above and your Trezor still isn't connecting, it may be time to contact Trezor support. Be prepared to share details like your operating system, browser version, Trezor model, and whether the device displays any messages.
Final Thoughts
Trezor Bridge is a vital but low-key part of your hardware wallet setup. When it fails, it can feel like your device is broken—but in most cases, it’s just a minor issue with software or browser configuration.
By following the steps above, you can usually fix Trezor Bridge issues in just a few minutes and get back to managing your crypto securely.
Always double-check that you're using official software, and if you're unsure, stick to Trezor Suite Desktop for the most reliable experience.
