Moxie Marlinspike's Perspectives addon for Firefox was a good attempt to resolve some of the problems with self-signed certs.

Unfortunately, no browsers adopted the project, and it is no longer compatible with Firefox. There are a couple forks which are still in development, but they are pretty underdeveloped.

I wonder if Mozilla would be more likely to accept this kind of project into Firefox today, compared to ~4 years ago when it was first released, now that privacy and security may be more important topic to the users of the browser.
