Mozilla is planning to include simple-text commands and desktop web apps in the next version of Firefox.
Firefox 3.2 will see the company build the Mozilla Labs project, Ubiquity, into the browser. Ubiquity allows users to type natural language phrases into the browser to perform certain tasks, such as typing "map 10 Downing Street" to instantly see a Google map of that address, or "share-on-delicious" to bookmark the site you're currently visiting on the social news site.
Other new features expected to arrive in Firefox 3.2 are "lightweight theming", which will allow people to customise the design of the browser without downloading separate extensions, and elements of another Labs project called Prism.
Prism is similar to a feature introduced with Google Chrome, which allows you to turn web apps such as Gmail into pseudo desktop apps, which are accessed from the Windows desktop or Start menu.
