Hello, after a discussion we had on IRC (I catch this occasion to announce the #icecat channel on the freenode.net network), it seems that themes could be considered "Arts" and it is not a problem if they are non-free.
Considering that Firefox themes don't contain only images but for example .css files too, is it a good idea to consider them "Art" files? Thanks, Giuseppe -- http://gnuzilla.gnu.org
