Socksv4 not supported?

[LosWheatleynDew]

Info

So apparently trying this on windows proxy it didn't want to work
However manually putting it on firefox works.
When i set socks to v4 on firefox it completely refuses to connect whilst putting it on v5 works fine

Error

Error: 
   0: An error occurred during the proxy handshake procedure
   1: invalid SOCKS version 01, expected 04
