Proxychains Not Working or Loading??

i really dont know what im doing wrong but when i type proxychains firefox (website) nothing happens

and this is my proxychains config ive combed over it and cant find any problems

# proxychains.conf VER 3.1

#

# HTTP, SOCKS4, SOCKS5 tunneling proxifier with DNS.

#

# The option below identifies how the ProxyList is treated.

# only one option should be uncommented at time,

# otherwise the last appearing option will be accepted

#

dynamic_chain

#

# Dynamic - Each connection will be done via chained proxies

# all proxies chained in the order as they appear in the list

# at least one proxy must be online to play in chain

# (dead proxies are skipped)

# otherwise EINTR is returned to the app

#

#strict_chain

#

# Strict - Each connection will be done via chained proxies

# all proxies chained in the order as they appear in the list

# all proxies must be online to play in chain

# otherwise EINTR is returned to the app

#

#random_chain

#

# Random - Each connection will be done via random proxy

# (or proxy chain, see chain_len) from the list.

# this option is good to test your IDS :)

# Make sense only if random_chain

#chain_len = 2

# Quiet mode (no output from library)

#quiet_mode

# Proxy DNS requests - no leak for DNS data

proxy_dns

# Some timeouts in milliseconds

tcpreadtime_out 15000

tcpconnecttime_out 8000

# ProxyList format

# type host port user pass

# (values separated by 'tab' or 'blank')

#
