Rated 5 out of 5 stars

I have been using Firefox for years and I am sure I tried to find Duden as an add-on a while ago, but failed. Strange, as it seems to be in existence for at least two years in its present form.

Anyway I found it now; it's a very useful complement to Leo and other such dictionaries.
(And this version weighs a lot less and takes up less space than the 'bookshelf' edition...)
