A browser extension is a computer program that extends the functionality of a web browser in some way. Depending on the browser and the version, 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.[citation needed]Microsoft Internet Explorer started supporting extensions from version 5.. Google Chrome started supporting extensions from version 4. The Opera desktop web browser supported extensions from version 10. The Apple Safari web browser started supporting native extensions from version 5. The syntax for extensions may be quite different from browser to browser, or at least enough different that an extension working on a browser does not work on another one. As for search engine tools, an attempt to bypass this problem is the multitag strategy proposed by the project Mycroft, a database of search engine addons working on different browsers.
