Feature For: Those who are too lazy to sit in their chair and wait a second or two for the contents of a web page to load when they click on the top-ranking page listed within Google’s search results.

Yes, instead of having to add extra seconds to your uncomfortable life of sitting in front of a computer, the contents of certain top ranking web pages will be prefetched when the actual search engine results are displayed.

Now Google’s faster than ever on Firefox and Mozilla browsers. When you do a search on these browsers, we instruct them to download your top search result in advance, so if you click on it, you’ll get to that page even more quickly.

Tool For: Those who are too lazy to highlight text and press ctrl-C.

Simple yet a very handy tool. Nothing sucks more than having to move your fingers over to hold down the control key and then pressing C to copy that text you highlighted. With this tool, all you have to do is highlight the text with your mouse cursor and that’s it. Still have to press CTRL-V to paste however . Maybe something is in the works for that as we speak.
