Trezor Bridge Not Working? Fix It Fast

If you're having trouble connecting your Trezor hardware wallet to your browser and keep seeing messages like "Trezor Bridge not running", you're not alone. Trezor Bridge issues are common, especially for new users or after browser/OS updates.

The good news? These problems are usually quick and easy to fix.

This guide walks you through the exact steps to troubleshoot and get your Trezor device working again — without stress.

What Is Trezor Bridge?

Trezor Bridge is the background service that allows your computer's browser to communicate with your Trezor hardware wallet. It's essential when using the web version of Trezor Suite or when connecting to other supported web wallets.

If Bridge is not working correctly, your browser won’t recognize the Trezor device, and functions like viewing balances, sending crypto, or signing transactions won’t work.

Common Signs That Trezor Bridge Is Not Working

Your browser does not detect the Trezor device
The website repeatedly asks you to install Bridge
Transactions fail to sign
Clicking "Connect" in the web wallet does nothing

Let’s go step-by-step to fix it.

Step 1: Restart Everything

Start with the simplest fix:

Unplug your Trezor device
Close all browser windows
Restart your computer
Open your browser again and reconnect your Trezor

Sometimes a reboot clears cached USB data and background conflicts.

Step 2: Reinstall Trezor Bridge

Go to and download the latest version of Trezor Bridge for your operating system. Once downloaded:

Install the software as instructed
Restart your browser after installation
Visit suite.trezor.io/web to test the connection

Step 3: Check That Trezor Bridge Is Running

After installation, Bridge runs in the background. You can verify it by:

On Windows: Opening Task Manager and looking for “Trezor Bridge”
On macOS: Using Activity Monitor and searching for “Trezor Bridge”
On Linux: Running ps aux | grep trezord in terminal

If Bridge is not running, try reinstalling it and restarting your machine.

Step 4: Try a Different USB Cable or Port

Faulty cables are often the root of the problem. Here's what you can try:

Switch to a different USB port
Use a high-quality USB cable that supports data transfer (not just charging)
Avoid using USB hubs or docking stations

Always connect the Trezor device directly to your computer if possible.

Step 5: Disable Browser Extensions Temporarily

Some browser extensions interfere with Trezor Bridge, especially:

Crypto wallets (like MetaMask)
Ad blockers
Privacy extensions

Open your browser in Incognito Mode with extensions disabled, or temporarily turn off extensions and try again.

Step 6: Use a Supported Browser

Trezor Bridge works best with:

Google Chrome
Mozilla Firefox
Microsoft Edge

Avoid using Safari or Brave for Trezor Suite Web — they may block necessary functions, causing device detection failures.

Step 7: Check System Permissions

Your operating system’s security settings may block Bridge from functioning.

On macOS:

Go to System Settings > Privacy & Security > Full Disk Access
Ensure “Trezor Bridge” has permission

On Windows:

Check firewall or antivirus settings
Make sure Trezor Bridge is allowed and not being blocked

Step 8: Use the Desktop Version of Trezor Suite

If browser-based access continues to cause issues, switch to the Trezor Suite desktop app. It connects directly to your Trezor device and does not require Trezor Bridge at all.

Download the latest version at and enjoy a more stable, native experience.

Reinstall Trezor Bridge from the official website
Use a different USB port or cable
