As I wrote there does not seem to be anything wrong with the content/css/html 
in the file index.html. I made another case. The folder with the files was 
entered in another apache server, so I could use http://localhost/test/
index.html to access that web page. Also in that case it works OK. The only 
difference with the case where it goes wrong is when I use https:// on another 
server to access that web page. So I believe it has something to do with how 
apache treats http different from https or it might be different treatment in 
Firefox.
