# WProofreader doesn't work in Zen browser

**Issue**

WProofreader may not work correctly in the Zen browser. Users can see a repeated sign-in prompt even after successfully logging in.

**Cause**

This is a known issue in the Zen browser. It affects browser extensions that use sign-in flows inside spaces or containers. The session isn't properly shared, which results in repeated authentication requests.

This behavior is not specific to WProofreader and also occurs with other extensions.

**Workaround**

To resolve the issue:

1. Open the **Sign in** page in a regular browser tab (not inside a container or space).
2. Complete the sign-in process there.
3. Return to your original tab and continue using WProofreader.

**Status**

This issue is tracked by the Zen browser team and is expected to be fixed on their side.
