What Is Trezor Bridge?
Trezor Bridge is a lightweight background application developed by SatoshiLabs that enables your computer’s browser to securely communicate with your Trezor hardware wallet, such as the Model One, Model T, Safe 3, or Safe 5. It replaces deprecated browser extensions like Trezor Connect and ensures compatibility across major browsers and operating systems. :contentReference[oaicite:0]{index=0}
Why Do You Need Trezor Bridge?
Browsers increasingly restrict direct USB access for security reasons. Trezor Bridge acts as a communication layer, facilitating encrypted data exchange between your hardware device and web apps like the Trezor Suite. It's essential when browsers lack native support for WebUSB, such as in Firefox, Tor Browser, or older web environments. :contentReference[oaicite:1]{index=1}

How It Works
Once installed, Trezor Bridge launches automatically and listens for connection requests from supported web applications. It acts as a secure gateway, forwarding encrypted messages without ever accessing or exposing your private keys, PIN, or recovery seed. :contentReference[oaicite:6]{index=6}
In effect, it transforms your computer into a safe communication hub—no data is visible to your browser; everything happens locally. :contentReference[oaicite:7]{index=7}

Why Trezor Bridge Is Secure
Trezor Bridge is open-source, cryptographically signed, and sandboxed, ensuring authenticity and safety. Users on communities like Reddit emphasize that even a malicious version cannot compromise funds—because sensitive actions must always be confirmed on the hardware device firsthand. :contentReference[oaicite:13]{index=13}

The Future of Trezor Bridge
As browser standards evolve, Bridge support may eventually be integrated directly into Trezor Suite, reducing the need for a separately installed component. But for now, it remains essential for reliable browser connectivity. :contentReference[oaicite:15]{index=15}
