Ubiquity (Firefox)
Ubiquity, a legacy extension for Mozilla Firefox, was a collection of quick and easy natural-language-derived commands that act as mashups of web services, thus allowing users to get information and relate it to current and other webpages.It also allowed Web users to create new commands without requiring much technical background.[4] Ubiquity had commands that allowed users to insert maps anywhere, translate on-page, highlight any code, and many other features.The global objects marshall application-wide services such as built-in command feeds.[7] The design goals for Ubiquity 0.5 focus on making it easier to experiment with new user interfaces and implement security measures.
