Convergence doesn't work with a proxy

[Jonny007-MKD]

Hello,
I often have to connect to the VPN of my university and they use a HTTP-proxy. When I try to visit SSL-encrypted sites through this proxy with convergence enabled the connection is reset. I get no SSL-error, but I noticed that it works when convergence is disabled in FF (clicking the icon for disabling doesn't change anything).
I already contacted the guys from my high school but I guess they will say it's not their fault ._.

Do they have a SOCKS proxy you could use?

[Jonny007-MKD]

Yes, but this proxy is protected with authentication and as far as I could find out FF doesn't support authentication for SOCKS 5.
At least I configured the SOCKS proxy and the problem stays the same. Of course I don't know if FF tries to connect to it...

The test for determing the type of proxy is quite strict in Convergence.
I had to change the SOCKS proxy test to support ssh -D tunneling
on my machine because firefox reports the connection as "socks4 "
(trailing space included).
