Fedora :: Java Engine For Browser - Add Exception ?

I want a internet browser to open a site that needs java engine,firefox has not this and also galeon :

The certificate is not trusted because it is self-signed.

(Error code: sec_error_ca_cert_invalid)

* This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.

* If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception

You should not add an exception if you are using an internet connection that you do not trust completely or if you are not used to seeing a warning for this server.

If you still wish to add an exception for this site, you can do so in your advanced encryption settings.

How i can add exception or it is better to say me that :is there any browser instead of internet explorer for linux??
