Disclaimer: - I'm no security expert but by installing Domino 9.0.1 FP2 IF1 you are enabling TLS v1.0 (and disabling SSL3 - kind of). See Darren Duke's Blog for some great information. also see this thread 

The only way to totally disable SSL3 in Domino 9.0.x is to use IHS - but IHS is now vulnerable to the POODLE TLS attack. IBM are yet to respond. 

I would suggest using Chrome to test. FF may still throw an error depending on the certificates you are using.

Disabling SSL v3 on Domino
A notes.ini setting is available to disable SSL v3.   It is:    DEBUG_UNSUPPORTED_DISABLE_SSLV3=17

This setting takes effect with a restart of any server tasks that are using SSL, such as HTTP.

If you use an IHS server in front of Domino, you can use TLS 1.2.   The Domino server at this time only uses TLS 1.0.
