Hi, i have FireFox v28. I was develop soks5 proxy and find some bugs on FF. I use options on FF soks5 proxy at 127.0.0.1:2002 and open site https://ssl.exelab.ru/f/

Here is an packets in bytes: [FF] 05-01-00 // FireFox say here that support one auth on free mode it's ok [S5] 05-00 // Soks5 accept connection in free mode [FF] 05-01-00-03-0D-73-73-6C-2E-65-78-65-6C-61-62-2E-72-75-01-BB // Here bugs

Bug #1 Why FF send address type IPv6? On my system i have only two network interface what support only IPv4. IPv6 has dissabled.

Bug #2 Wrong packet format. FireFox send only 12 bytes Protocol version: 05 Command type: 01 // connect Reserved: 00 Address type: 03 //IPv6 Address: 0D-73-73-6C-2E-65-78-65-6C-61-62-2E-72-75 // has only 14 bytes Port: 01-BB // SSL 443 In RFC1928 (http://www.ietf.org/rfc/rfc1928.txt) says what IPv6 must be 16 bytes!

Bug #3 Where FF took this address? It is not right. FF had to ask about the proxy address and address type using the command domain.

Thanks

127.0.0.1:2002 is your home network. I will assume that you are developing the sock5 proxy on your home network.

IPV6 is backwards compatible. If it is sending or asking for IPV6 address then the site that you are navigating to has an IPV6 associated with the dns name. Do you allow IPV6 in the about:config page? (network.dns.disableipv6 set to true? )

IPv6 addresses can be 16 or fewer, so this address is fine. Also the address comes from a reverse lookup gethostname() or in the case of IPV6() a domain ip6.arpa pointer is used. What is configured in Firefox how to connect to the network? Have you manually set up the proxy ip and port?
