Version 4.14 of Ant Video downloader now requires one additional permission webNavigation. This permission is used to properly display AVD icon when video detection is disabled. By design of Web Extensions API, when you set a new action icon, the web browser will reset it back to the one specified in the manifest when you navigate to a new web page. To prevent this from happening, AVD listens to navigation events and sets the correct icon, thus maintaining proper user experience.

You can safely click Update button to update AVD to version 4.14
