Google Toolbar for Firefox offers a Google search box (though this feature by default appears in FireFox ), search news articles, page rank, spell check, translator, and Google's AutoLink that turns street addresses into links to a map. Personally I like the page rank and translator feature. With Gooegle Toolbar now we just have to point to the word then the translation of the word will appear, useful and come in convenient. The green bar in the page rank feature gives you an idea of how high the webpage you are viewing is ranked in Google.
