Comment 9 for bug 187341

As of Firefox 3 Beta 5, and possibly new updates to Firefox 2, all self-signed certs are considered invalid, and is done in such a way that you can never bypass them. I encountered this when I recently updated Hardy. I hope that the firefox developers are looking into this, as when I search around, this bug is everywhere.

I'm facing the problem with my servers on the network that are self signed. Anyway, see:
