I've been experiencing the same problem. And changing security.enable_ssl2 to true in about
:config in firefox changed my problem from getting the error message mentioned earlier, to firefox default error message:
The connection was interrupted
The connection to test.domain.nl was interrupted while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in a few
* If you are unable to load any pages, check your computer's network
* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.
What would be the next step in trying to resolve this issue? I have followed all the steps in this forum. I want to use a self signed certificate but I just can't seem to get it to work.
