What are Chrome extensions?

Chrome extensions are software that can be installed into Google Chrome to change the browser's functionality. This includes adding new features or modifying the program's functionality to improve the user's efficiency.

An extension ensures a single purpose around which the whole program is built. Although it can have multiple components or be incorporated into a website, its function should help accomplish the program's primary purpose. To use an extension, a user must first download the .crx package, which is then installed. Extensions can be published in the Chrome web store.
