There was some time this morning and I found this perfectly spended on Ubiquity. The recently launched alpha of an awesome new firefox plugin. Have a deeper look at it by reading the User Tutorial.
I just played a bit around with the first steps presented in the Author Tutorial and compiled a quick Xing-Search Command.
You can grep the .js from my server and type CTRL-SHIFT "command-editor" and paste the small sniplet into the Command Editor
