No description provided.
This site intends to send a simplified, mobile-adapted site to some browsers. It is however not set up to recognise Firefox OS devices as smartphones. 

Here's some analysis of the HTTP traffic, showing how the backend sniffing sends less content to some smartphones than to the Firefox OS phone:

Significant difference in source code:
Smallest response has Content-Length: 5691
Largest response has Content-Length: 19604

Selected HTTP response headers (Firefox OS, Firefox on Android, Safari on iPhone):

Response for: 'Mozilla/5.0 (Mobile; rv:18.1) Gecko/18.1 Firefox/18.1'
Response Status: 200
content-length: 19604
content-type: text/html; charset=ISO-8859-1

Response for: 'Mozilla/5.0 (Android; Mobile; rv:26.0) Gecko/26.0 Firefox/26.0'
Response Status: 200
content-length: 5694
content-type: text/html; charset=ISO-8859-1

Response for: 'Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25'
Response Status: 200
content-length: 5691
