Allow embed Firefox to access SSL w/invalid certs
Just to add another .NET control to the list, MozNet (Se7en Soft Software) is an extended fork of the GeckoFX control. Offering many more features, although still suffers from the same SSL issue due to the default XulRunner builds being compiled without the needed support.
EDIT: As of MozNET R14 (soon to be released or possibly released by the time you read this) has support for adding SSL certificates without the messy file copy stuff mentioned above.
