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 127.0.0.1: 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.
