Trezor Bridge is an application which allows communication between the Trezor device and supported browsers.
The Trezor Bridge is a program designed to run in the background and requires no interaction.
When the Bridge is properly installed, you will be able to find the trezord process running in the background.
After you install Trezor Bridge with Firefox
for the first time, restart your browser. Without restarting, the browser might not be able to recognize your Trezor device.
Upgrading Trezor Bridge
As mentioned above, you can upgrade to the latest version of Trezor Bridge directly here. When there, click on .
Alternatively, check the GitHub repository.
When the upgrade is really necessary, there might be a notification in Trezor Wallet
Viewing Trezor Bridge status
To see the Trezor Bridge status, see the Trezor Bridge status page.
When switching from Trezor Chrome Extension
, remove the Trezor Extension from your browser and clear the cache (at least from wallet.trezor.io) after you install Trezor Bridge. The Bridge and the extension are designed to do the same thing, and if you have both of them installed, they sometimes tend to clash with each other. For the best possible experience, we recommend using Trezor Bridge, as the extension is now in end-of-life stage and is not being developed anymore.
