If you are proxying to mullvad servers on firefox or mullvad browser (or any other browser) using the mullvad browser extension or using proxy settings in firefox multi-account containers without first using a mullvad proxy host setting in browser settings then your dns will be leaking.

In this example i used italy server on mullvad app and usa proxy on mullvad extension in mullvad browser.

DNS Leak!

Blank browser proxy settings = DNS Leak

Mullvad browser extension and connection check website shows there is no leak when there is. At least it should flag yellow and give heads up to users "Hey look you might have a dns leak" and then give detail whether correct proxy settings have been applied.

Not everyone is advanced user so most users are going to be under false impression of security especially when mullvad extension and mullvad connection check page implies that everything is perfect.

To fix it:

When using WireGuard protocol:

SOCKS Proxy Server:

10.64.0.1 : 1080

When using OpenVPN protocol:

SOCKS Proxy Server:

10.8.0.1 : 1080

Apply correct settings

No more DNS leak!
