Tube Dimmer is a program that serves as an add-on to an Internet browser, created by Creative Island Media, LLC. The program adds the function for users to darken the area around a video window, creating a dimmed-lighting effect in the rest of the browser window.
After installation, Tube Dimmer adds a light-switch button on websites, to indicate that its function is applicable. The program is classified as an unwanted software, because it generates ads without the consent of the user. Tube Dimmer is also known to track the browsing habits of the user and to collect data, such as IP addresses, web pages visited and search queries made.
