# Enable Test Networks

In the Polkadot ecosystem, there are several **test networks**, including **Westend** and its associated system chains like **Westend People Chain** and **Westend Asset Hub**, as well as **Paseo Testnet** and others.\
Since test networks are intended for experimentation, they may occasionally experience issues that could affect the extension’s performance. We recommend proceeding with caution when using them.\
Test networks are **disabled by default**.

To enable them in the extension mode, open **Settings → Extension Settings →** on the **Main** tab toggle **Show Test Networks**, as shown below.
