Bug#766007: iceweasel: SSL error - cannot connect to certain servers

[Martin Hardcastle]

The latest Iceweasel security update disables SSL3 based on a
well-publicised vulnerability:
https://www.debian.org/security/2014/dsa-3050

This breaks a number of sites that only have SSL available for
encryption. I would personally have preferred a warning, but this is
really a problem with the sites using obsolete encryption algorithms,
not with Iceweasel.
