Hi Stefan,
The Chrome extension is part of the preview of EyeX for Windows, which is a separate software product that is in a pre-beta state. The easiest way for you to get in contact with the developers of this product is to send a support issue using the ‘Send feedback’ functionality that can be found by right-clicking the EyeX icon in the notification area. Please include your e-mail adress so they can get back to you for more details on the issue.
