Comment (by scissors):

 This is to do with how Torbutton checks if Tor is available. In your
 current setup, Torbutton is trying to connect to Tor's control port (to
 check your proxy settings) using the default port and password from Tor-
 Launcher; this fails because your system-wide tor process is using a
 different control port/password/cookie. You have a couple of options to
 work around this on windows:

 1) Completely disable Tor-Launcher in about:addons so that no default
 port/password is available. This will completely disable the New Identity
 feature, since requesting a new circuit requires control port access.
 Torbutton will now check Tor using check.torproject.org in the background
 and succeed.

 '''or'''

 2) Pass your system-wide Tor's control port/password/cookie to the browser
 on start-up. This is done by setting the environment variables
 TOR_CONTROL_PORT, TOR_CONTROL_PASSWD or TOR_CONTROL_COOKIE_AUTH_FILE (and
 maybe TOR_CONTROL_HOST). Torbutton will now be able to perform the control
 port check. Additionally new identity will now work. Note you must supply
 the control password in double quotes (e.g. "password" rather than
 password)

 Also see #11722.

 > Might be the same bug as #10178, I'm using Tor Browser 3.6.


 #10178 looks to have been caused by #10189, probably not related.
