What are browser extensions?
As the name suggest, browser extensions are an extension of the Web browser. The terminology however, maybe different for different browsers; for example you have Chrome Extensions and Firefox Add-ons.
Browser extensions are applications/programs that are run by the browser, inside the browser. So your application executes when the user starts the browser. They build customized features on top of the browser that can make a user’s life easy, enable him to do more stuff.
Why have extensions?
A browser in its base form provides only the absolutely necessary features and functionality for surfing the web.Extensions can provide more features on top of the basic browser functionality. These features can make a user’s life easier and enable him to do more stuff. This enables users to install only features they use, and not unnecessarily load the browser with useless (for the user) features.
For example, our Lean Library extension is only usefull for students and researchers who consume academic e-resources. So it's not a part of your standard browser, but can easily be installed on top of your browser.
