firefox-45 / 50 issues

[Jin Guojun]

10.3 Release has firefox-45 on initial installation. This firefox (45) does not support Chinese, which is displayed as squares.Does anyone happen to know how to make Chinese working on firefox 45?
Tried to upgrade to firefox 50.1.0_6,1 released today, but got following errors:
/usr/local/lib/libdbus-1.so.3: version LIBDBUS_1_3 required by /usr/local/lib/firefox/libxul.so not defined

 dbus 1.8.20 is currently installed. Does anyone one know which dbus release contains proper LIBDBUS_1_3 version string for firefox-50? 

Thanks,-Jin
