How add sock5 to tor browser

Hi , i cant add proxy(sock5) server to my tor browser. Its work only when i add to about:config http/ssl
server. But when i ad address to network.proxy.socks its doesnt work.

Unspecific to Whonix? If so:

Consider Generic Bug Reproduction.

ok, if i use proxychains and remove host 9050 and add another ip sock 5, it means the traffic will not pass through the track or it will pass through the tor and proxy I added?

proxychains is mentioned in documentation. Please read it.
