I spotted this create a Firefox search bar plugin how-to (via lifehacker) the other day, and it looked rather droll, so I lashed up a Firefox search plugin for here and then started on one for Wikipedia – as part of deciding whether it would be better to Google’s or Wikipedia’s own search for Wikipedia I had a quick search and found I was re-inventing the wheel.

Not only are there pre-existing search plugins for Wikipedia and dozens of other sites, but you can also create your own custom search plugin at Rollyo

Seems like it’s best to search before you leap…
