Found the problem in the html-pages. In each header-section is the following line:
<script type="text/javascript" language="javascript"/>
For me this looks okay, but this line is the reason why Firefox displays just a blank page. If you change the line to the following, everything works fine:
<script type="text/javascript" language="javascript"></script>
Has anybody an idea why Firefox has a problem with this?
Interesting would be what Sigil does, when you save the epub.
