Browser Extension

What Is a Browser Extension?

A browser extension is a plugin for an internet browser that adds additional functionalities and features to it that were not originally there or developed by the developers of the browser itself. Browser extensions have the capability to modify the user interface and add Web service functionality to a browser.

A browser extension can be considered as a small software unit, often referred to as a plug, that can perform various controls and filters to change the way a user can browse a web page or access information from a specific web service. 

It can utilize similar application program interfaces or APIs that JavaScript can on a web page, and browser extensions even have access to their own set of APIs.

In addition to enhancing website functionality, browser extensions can also be used to eliminate unwanted elements, such as pop-up advertisements and auto-play features in relation to online videos.
