How to Install and Use Trezór Bridge v22.9.3 — A Step-by-Step User Guide

If you’ve recently purchased a Trezór hardware wallet or are trying to reconnect your existing device to web apps like Trezor Suite, MetaMask, or your favorite DeFi platform, you’ll likely come across a critical piece of the puzzle: Trezór Bridge.

With the release of version 22.9.3, Trezór Bridge has become even more reliable and secure — but how do you actually install it and start using it?

Don’t worry — whether you're brand new to crypto or just want to make sure you’re doing things right, this guide will walk you through every step of installing and using Trezór Bridge.

💡 What Is Trezór Bridge?

Trezór Bridge is a background application that allows your web browser to securely communicate with your Trezór hardware wallet. Without it, your device might not be detected properly by certain apps, especially in browsers like Chrome, Firefox, or Brave.

Trezór Bridge is required for:

  • Trezor Suite (browser version)

  • Connecting Trezór to third-party wallets like MetaMask

  • Using Trezór on DeFi platforms (Uniswap, Aave, etc.)

✅ Step 1: Check Your System Requirements

Before installing, make sure your computer meets these basics:

  • Operating System: Windows 10/11, macOS 10.15 or later, or a Linux distro (Ubuntu, Fedora, etc.)

  • Browser: Chrome, Firefox, or Brave (latest version recommended)

  • Trezór Device: Model One or Model T (firmware up to date)

🔽 Step 2: Download Trezór Bridge v22.9.3

  1. Head to the official site: https://trezor.io/start

  2. Choose your operating system (Windows, macOS, or Linux).

  3. Click Download Trezór Bridge.

  4. You’ll receive a .exe, .dmg, or .tar.gz file depending on your OS.

💻 Step 3: Install Trezór Bridge

For Windows:

  • Double-click the .exe installer.

  • Approve the installation when prompted.

  • Once installed, it will run in the background automatically.

For macOS:

  • Open the .dmg file.

  • Drag the Trezór Bridge icon into your Applications folder.

  • You might need to allow the app through macOS security settings (System Preferences > Security & Privacy).

For Linux:

  • Extract the .tar.gz file and run the install script via terminal.

  • You may need root or sudo privileges.

🌐 Step 4: Restart Your Browser

This is super important! After installing Bridge, completely close and reopen your browser so it can detect the new service.

  • Chrome: Close all windows, then relaunch.

  • Firefox: Same — restart fully.

  • Brave: Relaunch from the dock or taskbar.

🔌 Step 5: Connect Your Trezór Device

  • Plug in your Trezór via USB.

  • Unlock it using your PIN if prompted.

  • Open Trezor Suite Web or the platform you’re using.

  • You should now see your device appear — no browser extensions needed!

🔧 Step 6: Troubleshooting Tips

If your device isn’t being detected after install:

  • ✅ Confirm the USB cable is working (some charging cables don’t transmit data)

  • 🔁 Try a different USB port

  • 🔐 Check that your browser has permissions enabled for localhost communication

  • 🔄 Reboot your computer and try again

  • 🔒 If using Brave, turn off “Shields” temporarily for Trezor sites

You can also visit https://127.0.0.1:21325/status/ to see if Bridge is running.

🔁 Step 7: Updating Trezór Bridge

Already have an older version installed? Here’s how to update:

  1. Visit the Trezór Bridge download page

  2. Download the latest version (22.9.3)

  3. Reinstall it — your old version will be replaced

  4. Restart your browser

There’s no need to uninstall manually unless troubleshooting an issue.

🔐 Final Tip: Security Best Practices

  • Only download Trezór Bridge from trezor.io

  • Never install third-party versions

  • Keep your device’s firmware and Bridge app updated

  • Always double-check URLs when connecting your wallet to new dApps
