[b2g] b2g, text/vnd.wap.wml and UX

When accessing Web sites, sometimes Firefox OS is identified as a basic feature 
phone and is being sent to the WAP site. (below an example of that)


On Firefox OS, 
* the user gets a blank page. That's not very helpful. There should be a better 
way to inform the user that there is an issue. 
* the developer should receive a message in the console saying that the format 
text/vnd.wap.wml sent by the server is incompatible with Firefox on Firefox OS.

Should I open a bug?

PS1: On Firefox for Android, the message is no better. You noticed that 
something has been downloaded and that's all.
PS2: On the Web Compatibility side, we attempt to get things fixed by 
contacting Web sites, but the user experience is still crappy if we don't get a 
quick fix.


Example:

→ http -v  GET http://wap.abchina.com/Portal/logon/Index.aspx  "User-Agent:

"Accept-Language:  en-us,en;q=0.5" "Accept-Encoding: gzip, deflate" "DNT: 1" 
"Connection: keep-alive"
