What is Add-On


An add-on, also known as an add-on or extension, is software that is installed in a main program to add new features and improve its performance. Typically, add-ons are small pieces of code that allow users to customize their experience of using a software, adding extra features that are not present in the original installation of the program.

Add-ons are very popular in web browsers, such as Google Chrome and Mozilla Firefox. These browsers have a large number of add-ons that allow users to block advertising, download videos, improve privacy, among other functions.

Types of Add-ons

Add-ons can be classified according to their functionality:

  • Ad blockers: are add-ons that prevent the appearance of pop-ups and advertisements on web pages. This allows for smoother navigation and faster page loading speeds.
