This plugin replaces the standard scrollbar with a more modern, skinnier, and less interfering one. This is modeled after the scrollbars used by Google in many of their services.
Explanation of "all data on all websites":
For the extension to apply a scrollbar to any site, it must have the ability to modify the css for the current page. This means that "all websites" are injected with the appropriate styles.
