Cantonese-English pop-up dictionary for ChromeCantonese-English pop-up dictionary for Chrome. Simply hover the mouse pointer over Chinese words to have both the definition and pronunciation displayed via a pop-up window in real-time. Pronunciation is displayed as Yale romanisation with tone numbers (other configurations are not supported at this time).
This plugin is based on the "Perapera Chinese Popup Dictionary" plugin for Chrome (which is in turn based on several other projects including Rikaikun, Rikaichan and RikaiXUL), with the dictionary replaced with data from Cantonese CEDICT project. The original copyright notices remain intact within the package source files. I take no credit for this; it was a quick and easy hack using existing resources.
