# 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.
