Uninstalling and Reinstalling Trezor Bridge: A Step-by-Step Guide

If you're having trouble connecting your Trezor hardware wallet to your browser or desktop interface, there's a good chance the issue lies with Trezor Bridge. Bridge is the background service that enables communication between your Trezor device and your computer. Over time, outdated or corrupted installations can lead to connection issues, especially after browser or OS updates.

In most cases, uninstalling and reinstalling Trezor Bridge can resolve connection problems and restore stable performance. This guide walks you through the process, whether you’re using Windows, macOS, or Linux.

What Is Trezor Bridge?

Before diving into the how-to, let’s quickly recap what Trezor Bridge does. It’s a lightweight piece of software developed by SatoshiLabs that facilitates secure communication between:

  • Your Trezor hardware wallet
  • Your web browser
  • And, optionally, Trezor Suite (the desktop wallet)

Trezor Bridge runs quietly in the background, and it's required for browser-based wallet access unless you’re using WebUSB (which works without installing anything, but only on Chrome/Chromium).

When Should You Reinstall Trezor Bridge?

You should consider uninstalling and reinstalling Trezor Bridge if:

  • Your Trezor device isn’t being recognized in the browser.
  • You receive a "Bridge not running" or "Device not found" error.
  • Bridge seems to crash or freeze during use.
  • You recently updated your operating system or browser and the device stopped connecting.
  • You switched from using WebUSB back to Trezor Bridge.
