Firefox will find search engines for you!
One nice feature of Firefox 2 that i think gets overlooked by a lot of people, is the quick and easy way you can find new search engines via the browser. When a Web site has made a Firefox 2 compatible search, your search bar should glow or so something else (I think it changes from theme to theme). Not sure what to look for?
The folks over at Lifehacker have put together a video to watch just in case you are not sure. Worth watching – just to make sure!
