Add Other Services to Google Search
If you install the “Greasemonkey” Firefox plug-in, you can then install a useful script that will add a sidebar to Google search with search results from Youtube, Wikipedia, and Dictionary.com. You can download Greasemonkey from https://addons.mozilla.org/en-US/firefox/addon/748, and then install the Google sidebar script from http://userscripts.org/scripts/show/44397. I’ve been using this for a couple of weeks, and find it quite handy to have the extra search results on the sidebar! If you try it, add a comment and let us know what you think.
