An add-on is a module which may be added onto a larger application (usually a Web browser). Add-ons are normally developed by third parties; however, this presents a risk of unintended side-effects as the different components cannot be tested in all possible configurations. There are three types of add-ons: extensions, plug-ins, and themes.
