Document type / content type problems

[Kiril Angov]

Hello list,

I have a strange problem where one of my domains is experiencing
problems. The problem is that under Firefox, it gives me a prompt to
download the file rather than displaying it in the browser window. The
same domain works just fine under Safari or IE. I thought there is
some problem with the headers or something but I tried all I could and
the problem is still here:

if I do "curl -i" I get:

HTTP/1.1 200 OK
Server: nginx/0.6.30
Date: Thu, 01 May 2008 02:51:41 GMT
Content-Type: text/html; charset=utf-8
Content-Length: 4082
Last-Modified: Thu, 01 May 2008 01:18:04 GMT
Connection: keep-alive
Accept-Ranges: bytes

The domain in question is icepique.com

I do not even know what info to provide as I do not know what is
relevant so if you know what I should check first, let me know and I
can provide more info.

Thanks in advance,
Kiril
