(Firefox :: Untriaged, defect)

Description

[Andrey K]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:15.0) Gecko/20100101 Firefox/15.0.1
Build ID: 20120905151427

Steps to reproduce:

Go to the site http://opennet.ru (lightweight version of www.opennet.ru).
Follow some news item that lead to a news page on main version of site (www.opennet.ru).
After that if I type "opennet.ru" or "http://opennet.ru" in address field, Firefox automatic adds "www" part and direct me to www.opennet.ru - unneeded site face.

How to reproduce:
1) open firefox with fresh profile;
2) go to the opennet.ru;
3) open new tab and close previous;
4) type opennet.ru in address field -> see same site face;
5) go to some news item;
6) open new tab (and close previous if you want);
7) type opennet.ru in address field;
8) view www.opennet.ru instead of opennet.ru.

OS: Debian Squeeze


Actual results:

"www" suffix/prefix is appended/prepended to address without it.


Expected results:

If site has active two-words (word-dot-word) domain and user not types "www", browser must goes exactly to that address.
