Firefox proxy connection settings

NNTP-Posting-Host:  121.6.200.187

when I want to change the connection settings of the proxy, the entire connection settings windows does not allow me to check any box, meaning that the whole window is grey.May I know how do I enable the window so that I can change the proxy connection settings?
