Do you have wikipedia in your firefox search box?

If you have off the wall discussions in your workspace like we do in our programmer 'corral' in the office, being one click away from an answer is a necesity. see: Pininfarina and Turpentine

To make 4 clicks now, and save more later, click on the seach engine icon (probably a big "G") in the seach input field and choose 'add engine'. you should see the link to add wikipedia (and others).

Then you can choose wikipedia from the dropdown list.
