William Tan, aka =wil, aka dready, has taken his Firefox XRI extension — FoXRI — and made it a SourceForge project! Here’s relevant links…

This extension enables Firefox to process XRIs entered directly into the Location bar. Try it out, it’s very cool. And join the project if you have a hankering to learn more about XRIs and want to more fully realize their enablement in Firefox.
