2)  Go to control panel, java, click on the security tab, click edit site list, and add the URL to your Firewall.  Make sure you include "https://"

3)  If that doesn't resolve it, make sure 3des is enabled in "show version" on the ASA.

4)  If it is, issue these commands-
ssl server-version any
ssl client-version any
ssl encryption rc4-md5 rc4-sha1 aes128-sha1 aes256-sha1 3des-sha1
ssl certificate-authentication fca-timeout 2

5)  If that doesn't work, issue these.  Use your own username and password.
aaa authentication http console LOCAL
