Sticky Notes, for example, is a Google Chrome browser extension that makes it easy to take notes inside Chrome as you read articles or watch videos. There are also extensions that capture and edit screenshots in your browser, check your spelling, display the lyrics for YouTube music videos, and much more. Browser extensions are only available for desktop versions of Chrome. Extensions do not work with the Chrome mobile apps.
