Typing search words in Firefox URL bar

Hey, I just found something cool. I wanted to find the web site for the Samsung MM-A900 cell phone that I found from CNET (I just wrote a post earlier), and do a search on the Google search bar in Firefox. However, I accidentally put in the Firefox URL bar, and when I pressed enter it directed me to this page on the Samsung MM-A900 cell phone. I didn't know that you could do that with Firefox! Another great reason I use Firefox as my main browser and not Microsoft Internet Explorer, among also other things (like tabbing, being fast, extensible plugins, non-Microsoft, etc.).
