[Firefox only] I stumbled into this application the other day and decided to give it a whirl – and boy, is it ever handy. It places the power of Google Search services such as image, news and web search in the address bar of Firefox to allow for easy searching from any web site you please.
The coolest feature though, is the fact that you can restrict the results to a specific domain such as “en.wikipedia.org” which will only display google results for that web site. Also, you have the ability to place your favorite favicon in the results of the drop down menu. Check out the video below to see the add-on in action.
Nice feature! Although in wikipedia’s case, most things you search in google usually come up with wikipedia anyway.
But having said that, the wikipedia search thing is horrible and having a “google powered wiki-specific search engine” would be great!!
Anyway, all the best!
