Trezor Bridge® for Chrome, Brave, Firefox – Official Setup

Cryptocurrency security is paramount, and hardware wallets like Trezor® provide a safe, offline way to store your digital assets. To fully utilize your Trezor device with web browsers such as Chrome, Brave, and Firefox, you need Trezor Bridge®—the official connectivity software that allows your device to communicate securely with your computer and web apps.

This guide explains what Trezor Bridge® is, why it’s necessary, and how to install, configure, and use it safely with multiple browsers. By following these instructions, you ensure seamless and secure access to your Trezor wallet for managing cryptocurrencies.

What Is Trezor Bridge®?

Trezor Bridge® is a small software application developed by SatoshiLabs, the creators of Trezor hardware wallets. It acts as a bridge between your Trezor device and compatible web browsers, enabling features such as:

  • Secure device communication
  • Transaction signing
  • Accessing Trezor Suite Web and other supported web apps
  • Plug-and-play connectivity without relying on browser extensions

Trezor Bridge® replaces older browser extensions, providing a more secure and reliable way to connect Trezor wallets to the web.

Why You Need Trezor Bridge®

Web browsers cannot communicate directly with Trezor devices due to security restrictions. Trezor Bridge® solves this by creating a local communication channel. Without it:

  • Your browser cannot detect the device
  • Transaction signing and account management are unavailable
  • Hardware wallet features are limited

By installing the official Trezor Bridge®, you ensure your hardware wallet operates safely, without exposing private keys online.

Supported Browsers

Trezor Bridge® works with all major browsers, including:

  1. Google Chrome – Fully supported for desktop use
  2. Brave – Secure and privacy-focused, compatible with Bridge
  3. Mozilla Firefox – Compatible for Windows, macOS, and Linux

It is recommended to always use the latest browser version to avoid compatibility issues and security vulnerabilities.

When connecting for the first time:

  1. Your browser will prompt a connection request
  2. Confirm on your Trezor device by entering your PIN
  3. Approve the connection to allow the web app to communicate with your wallet

This step ensures that your Trezor remains secure and only authorized apps can access it.

Trezor Bridge® allows you to use your hardware wallet across different browsers without reinstalling:

  • Chrome: Works seamlessly with Trezor Suite Web and other crypto apps

  3. Keep Firmware Updated: Your Trezor device should have the latest firmware installed via Trezor Suite
  4. Avoid Public Networks: Use secure private networks when accessing web wallets

Following these practices minimizes risk and keeps your crypto assets safe.
