I tried many SOCKS4 proxies from 
http://sockslist.net/proxy/server-socks-hide-ip-address and mostly I am 
getting this error:
Error 120 (net::ERR_SOCKS_CONNECTION_FAILED): Unknown error.
Only one of them succeeded.
SOCKS5 however works ok.

On firefox I am getting similar symptoms, it can't connect to most 
SOCKS4 proxies and can connect to SOCKS5.

What might be a problem? I was thinking that maybe some system or port 
library has some issue related to SOCKS4? Maybe libssl.so ?
