Firefox: Ubiquity, the experimental Firefox extension that works as an ultimate Firefox command line, grows into a 0.5 release with better non-English language support, smarter parsing of text input, and, perhaps best of all, a helpful step-by-step tutorial for newcomers.

English language users will be most interested to hear that multi-word Ubiquity commands no longer require hyphens, the result of a new parsing engine being worked up for this release. That engine can also make asynchronous, or as-you-type, network calls to bring up preview results much faster, and bases the top few suggested commands on the weight of the nouns one enters. What's really neat, though, is an interactive, web-based tutorial that walks a new user inch by inch through Ubiquity, from learning how to trigger it with the keyboard all the way through translating blocks of text on the fly from simple mouse selections. You can access that tutorial by hitting the "Preferences" button on the Ubiquity listing in Firefox's Add-Ons window.

International users also get better language support, and Mozilla's offering up a localization tutorial to help anyone teach their Ubiquity how their language works.

Ubiquity 0.5 is a free download, works wherever Firefox 3.0 or 3.5 does. Find something else new and noteworthy in this release? Tell us about it in the comments, and be sure to swing by the Ubiquity Herd to search and try out new commands.
