When a user requests a particular website, the web browser retrieves the necessary content from a web server and then displays the resulting web page on the user’s device.
Web browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones.
In 2019, an estimated 4.3 billion people used a browser. The most used browser is Google Chrome, with a 64% global market share on all devices, followed by Safari with 17%.

A browser extension / Add-ons/plug-in is a small software module for customizing a web browser.
These extensions/add-ons/plug-ins are used to extend the features or capability of browsers.
Browsers typically allow a variety of extensions/add-ons/plug-ins, including user interface modifications, ad blocking, and cookie management.
Browser plug-ins are a separate type of module.
The main difference is that extensions are usually just source code, but plug-ins are always executable (i.e. object code).
As of 2019, plug-ins have been deprecated by most browsers, while extensions are widely used.
The most popular browser, Google Chrome, has thousands of extensions available but only one plug-in: the Adobe Flash Player which is disabled by default.
