Browse faster by speeding up common tasks.
FastestFox (formerly SmarterFox) is one of the more powerful add-ons to enhance Firefox browsing. It displays a clean-looking bubble filled with customizable search engine shortcuts when you highlight a word or phrase. Type a query into the Firefox address bar, and FastestFox will offer up suggestions as you type. It will also place alternative search engine icons on a results page (like Google, Yahoo, and Bing), and will repeat smaller version of those icons on Wikipedia pages, along with a list of related articles. To open a new Web page faster, there's the qLauncher. One hot-key combo brings it up; tapping a single keyboard key opens Facebook, the New York Times, and whatever else you program in.
