By moving the mouse cursor, a translation appears on the sidebar. FireDictionary finds the translation as a real-time operation when you move the mouse cursor.

FireDictionary uses English-Japanese dictionary GENE95 as a dictionary content, which contains 57,350 words. It's fast to find the translations because the dictionary content is on your PC.

FireDictionary is an extensible platform for multidictionaries. We can also add another dictionary using JavaScript.
