The Zhongwen Chrome extension, which provides an easy to use Chinese popup dictionary, is now available in German and in French.
Both new versions support adding words to your Skritter queue, just as the English version does.
The German version is based on HanDeDict with about 150,000 entries. The French version uses CFDICT with more than 100,000 entries.
