Browser extension

Definition

“A browser extension is a computer program that extends the functionality of a web browser in some way. Depending on the browser, the term may be distinct from similar terms such as plug-in or add-on. Mozilla Firefox was designed with the idea of being a small and simple web browser, delegating more advanced functions to Mozilla extensions.” (Wikipedia, retrieved 10:11, 19 March 2009 (UTC)).
