Debugging is a troubleshooting tool that helps Mozilla’s engineers see what has gone wrong with the VPN so that they can fix it. If you’re having problems with Mozilla VPN, Mozilla Support may ask you to use the debugging tool to export the application logs.

How to export logs on Mozilla VPN

Follow these steps to export the application logs:

Open Mozilla VPN and click the gear icon (icon may appear in top right corner of the application on versions older than 2.10).

Select View Log. This will generate a .txt file with logs to help Mozilla Support troubleshoot the problem.
Attach the .txt file to your Contact Support Form.
