Browser extension
A browser extension is a plug-in that extends the functionality of a web browser.
 Some extensions are authored using web technologies such as HTML, JavaScript, and CSS.
 Others are developed using machine code and application programming interfaces (APIs) provided by web browsers, such as NPAPI and PPAPI.
 Browser extensions can change the user interface of the web browser without directly affecting viewable content of a web page; for example, by adding a browser toolbar. Userscript
