Trezor Bridge was a small background application created to facilitate secure communication between a Trezor hardware wallet and a web browser or desktop app. It exposed a local HTTP endpoint so web pages (or desktop software in web mode) could talk to your Trezor device even when direct browser USB support (WebUSB) was limited. The Bridge acted as a translator and transport layer between the device firmware and host applications.
Load-bearing fact: Trezor’s official documentation confirms that standalone Trezor Bridge has been deprecated and users are recommended to uninstall it in favor of newer integrations (Trezor Suite / nodeBridge / WebUSB). :contentReference[oaicite:0]{index=0}
When Trezor devices first reached mass usage, browser support for secure USB communication was inconsistent across platforms and browsers. Bridge solved that by running locally and exposing an API the browser could call. Over time, browsers added WebUSB support and Trezor improved server-side tooling (like trezord / nodeBridge), and the Trezor team integrated much of Bridge’s functionality into the Trezor Suite or into new transport layers.
As of the latest official guidance, standalone Trezor Bridge is deprecated: Trezor encourages users to use Trezor Suite (desktop or web) which includes modern transport layers and provides a smoother, supported experience. If you still have old Bridge installations, Trezor provides uninstallation instructions for Windows, macOS, and Linux. :contentReference[oaicite:1]{index=1}
Deprecated software left running on a machine can cause conflicts, degrade UX, or even block newer transports. Uninstalling Bridge and moving to Trezor Suite avoids compatibility problems and keeps your device working with the latest OS/browser changes. :contentReference[oaicite:2]{index=2}
Historically, installing Trezor Bridge was straightforward: visit the official Trezor download page, pick the right installer for your OS, and run it. For modern setups, though, the recommended path is to download and use Trezor Suite (desktop) or use the web app where supported — both will include the necessary transport support and remove the need for a separate Bridge install in many cases. :contentReference[oaicite:3]{index=3}
Download the Windows installer from Trezor (or install Trezor Suite) and run the executable. If you have a legacy Bridge installer and need to remove it, use Programs & Features to uninstall. :contentReference[oaicite:4]{index=4}
Download the PKG or Trezor Suite .dmg from trezor.io and follow the installer prompts. Older Bridge installations provided an uninstall.pkg for removal. :contentReference[oaicite:5]{index=5}
Bridge was available as a package (apt/homebrew, etc.). Modern distributions should prefer the Trezor Suite or nodeBridge integrations; if you installed a package named trezor-bridge, you can remove it with your package manager (for Debian/Ubuntu: sudo apt remove trezor-bridge). :contentReference[oaicite:6]{index=6}
If you still have standalone Bridge installed, Trezor’s guidance is to uninstall it because future releases of Trezor Suite and browser-based flows may not work correctly with old Bridge binaries present. Uninstall steps differ per OS (Windows: uninstall.exe or Programs & Features; macOS: uninstall.pkg; Linux: package manager). After uninstalling, restart and install Trezor Suite if needed. :contentReference[oaicite:7]{index=7}
Many "device not detected" problems are simple: faulty USB cable (charging-only), damaged port, blocked browser extension, or missing permissions. Try a data-capable USB cable, different port, and a clean browser profile or system restart. If using Trezor Suite, ensure you have the latest Suite version and that your device firmware is up to date. Community reports and official guides cover common pitfalls and fixes. :contentReference[oaicite:8]{index=8}
If after all steps the device is still not recognized, contact official Trezor Support or consult the community forum (links below). :contentReference[oaicite:9]{index=9}
Since Bridge runs as a local service, always download installers only from official sources (trezor.io or Trezor's official GitHub). Avoid third-party downloads. Deprecated binaries may contain outdated code—another reason to remove them and switch to official, maintained apps. When in doubt, verify hashes/signatures if provided on the official site.
Trezor's official documentation stresses using official channels and warns that standalone Bridge is deprecated to avoid conflicts and security surprises. Keep firmware and apps up to date to retain the latest protections. :contentReference[oaicite:10]{index=10}
Modern Trezor workflows favor:
If you build integrations (developers): prefer official libraries and transports maintained by Trezor or documented in their developer guides instead of relying on deprecated Bridge endpoints.
Tip: always prefer the official trezor.io pages or the official GitHub repositories when downloading software or following developer docs.
For new users: skip installing standalone Bridge — download Trezor Suite and follow the official start guide. :contentReference[oaicite:23]{index=23}
For users who have old Bridge installed: uninstall it following Trezor's deprecation guide, then install the latest Trezor Suite or confirm your use-case is supported by nodeBridge/WebUSB. Back up your recovery/wallet backup before making any major changes to software or firmware. :contentReference[oaicite:24]{index=24}
If you develop integrations, migrate away from any deprecated Bridge endpoints and adopt the official transport libraries or server pieces Trezor documents (trezord / nodeBridge). Check the official GitHub repos and developer pages for up-to-date recommendations. :contentReference[oaicite:25]{index=25}
