Tor is free and open-source software that enables anonymous communication.

Tor Browser is a fork of Firefox, which is carefully configured to access the Internet only via bundled Tor client.

Using Trezor Wallet with Tor Browser[edit]

When using Trezor Wallet with Firefox (which is a base for Tor Browser), we cannot use WebUSB (like in Chrome), but we need to use the Trezor Bridge. Please follow the instructions on the Bridge page to install it.

Tor Browser routes all traffic via Tor by default, and the Trezor Wallet cannot directly contact the Trezor Bridge. Luckily, we can add an exception telling Tor Browser to communicate with the Bridge.

You need to use Tor Browser 9 or newer!

Instructions for enabling Trezor Bridge in Tor Browser[edit]

In Tor Browser 9 and newer, the required changes need to be done in the advanced settings.

  1. Type about:config in the address bar
  2. Search for the key network.proxy.no_proxies_on
  3. Set the value to
  4. Search for the key network.http.referer.hideOnionSource
  5. Set the value to false

Instructions for using Trezor services in Tor Browser[edit]

You can now use the following Trezor services:

name regular url onion url
Trezor Walet http://wallet.trezoriovpjcahpzkrewelclulmszwbqpzmzgub37gbcjlvluxtruqad.onion
Trezor Suite http://suite.trezoriovpjcahpzkrewelclulmszwbqpzmzgub37gbcjlvluxtruqad.onion

Regular URLs use HTTPS, while onion services do not use HTTPS but plain HTTP (encryption is guaranteed by the underlying Tor protocol).

Quick check for the onion address: it starts with "trezorio" and does not contain any numbers except for the "37".
