Google Translate

This extension adds a button to your browser toolbar. Click the translate icon whenever you want to translate the page you're visiting. The extension also automatically detects if the language of a page you're on is different from the language you're using for your Google Chrome interface. If it is, a banner appears at the top of the page. Click the Translate button in the banner to have all the text on the page appear in the new language. Google Translate is in the Chrome Extensions category of the Browsers section.
