From the developer:
Translate This ! extension for Firefox lets you translate an entire we-page or just a selection of it using Google Translate. Just select the text you need to translate and click " Translate This Selection" to get definition in other languages. Because of limitations of Google Translate, translating entire pages will not work if the page is HTTPS.
