Xubuntu 14.10-64
Transmission (GUI) 2.84 (14307)
Firefox 35.0.1
In Transmission`s options I switch-on Remote control and write port, login, password, IP.
Then try to "Open web-client"-button - and in Firefox I see small window "Login-Password".
I wrote login and password - but web-client do not opened.
On Firefox-page I see: "401: Unauthorized and Unauthorized User"
How can I open web-client?
