A browser extension is a small software program that adds to or changes what a web browser can do. Depending on the extension, it might add a browser feature, alter part of the interface, or change what appears on a web page.
What does a browser extension do?
Extensions augment a browser: they can add features, change interface behavior, or modify and enhance web page content. Mozilla describes an extension as software that “adds features and functions to a browser,” while the W3C describes extensions as small applications that run within a browser. These are possible uses, not things every extension does.

- An extension might add information or a tool to the browser.
- It might change how part of the browser interface works or looks.
- It might alter or enhance content on a web page.
The specific behavior depends on the extension. Some work mainly in the browser interface; others act on websites, and some do both.

Extensions are commonly built with HTML, CSS, and JavaScript, along with browser extension APIs. Those APIs provide capabilities beyond ordinary JavaScript running in a web page. What an extension can do is still subject to the browser platform and the permissions it requests; an extension does not automatically have unrestricted access to browser features or user data.

Are extensions and add-ons the same thing?
In everyday browser language, “add-on” is often used to mean an extension. The terms are not identical in every browser’s documentation, however. Mozilla uses “add-ons” as a broader category that includes different types of components, with extensions as its most common type. Check a browser’s own terminology when looking for or managing one.
Do browser extensions work in every browser?
WebExtensions APIs are broadly compatible across major browsers, including Chrome, Safari, Edge, and Opera, but compatibility is not a guarantee that every extension works unchanged everywhere. Browsers may support different APIs or implement behavior differently, so an extension may need adaptation for another browser. Check its listing or documentation for the browsers it supports.

What is a browser extension not?
An extension is software that runs within a browser, not a separate browser itself. It is also not necessarily something that changes web pages: adding or modifying page content is one possible function among several, alongside adding browser features or changing interface behavior.
