I was using firefox to access a new Sharepoint site with a port number:
http://[url]:6000
then
"Erro 312 (net::ERR_UNSAFE_PORT): Erro desconhecido."
What a strange error, this only happen on Firefox and Chrome, IE works fine
The problem: Firefox and Chrome have security properties about ports diferent 80 and block access....
So how to override this situation,
After a litle search a College sugest me this solution, only work with Firefox,
On url write
"about:config"
click next
add new Property "String"
network.security.ports.banned.override
Then add the port Number:
6000
and now works like a charme....
