I also heard that Firefox enjoys a major market share in Germany (a not-that-reliable source is http://www.quora.com/Why-is-Internet-Explorers-market-share-...). I even heard from a fellow German university student that "everyone [in Germany] uses Firefox" - obviously an exaggeration, but there must be some truth in it.
Anyone has an explanation (preferably backed by data) for the popularity of Mozilla software in Germany?
