Hi Emy, thanks for reaching out.. i am afraid that for the time being we do not offer a dedicated web browser extension in conjunction with the Tobii Device, however you can continue to use the Windows Interaction Tools such as Mouse Warp, etc to interact with the browser as if you were working with any other application.
Have you already tried using the Standard Tobii Software and have hit some issues? Please let us know of your experiences and we will do our best to help you out. Best Wishes.
