Firefox's Ubiquity is like Quicksilver for the Web

I'm a big fan of Quicksilver, an application launcher for the mac (that's really an understatement, because you can do a so much more than just launch applications, but I digress).  So when I came across this Firefox plugin called Ubiquity the other day, I became immediately excited.  Ubiquity is like Quicksilver for the web.  It allows users to tell the browser, through language, what they want to do.  What does this mean exactly?  Check out the video below:

I decided to dig a little deeper to see how hard it was to create my own Ubiquity plugin.  It turns out to be surprisingly simple.  I wrote a little script that allows you to validate any webpage's html or css on-the-fly (which I find extremely useful in quickly testing our developer's front-end code).  You can download it from our software section here.  

Ubiquity is still very experimental and in it's early stages of development, but once you start getting a feel for it, you'll begin to think of how this little plugin can simplify a lot of the web-based tasks you execute on a daily basis.  I for one, am very excited about the possibilities.
