The Hyperwords Company has released Hyperwords 5.0. Hyperwords is a Mozilla Firefox web browser Add-On and is fully customizable. When the user selects any word, sentence, or paragraph, a menu appears which allows the user to carry out web-searches, language translations, and unit conversions. Results can be viewed directly in the menu, or opened in a new browser window. Other operations such as language translations and unit conversions can directly modify the displayed webpage.
