The way Chrome handles SSL certs on Linux has always driven me crazy. My company's firewall uses a man in the middle SSL certificate so on most SSL sites I have to "proceed anyway" everytime I restart my browser. Chrome on Linux can't seem to permanently store the exceptions, even with every certutil command known to man.

This in itself wouldn't be all that bad, the real problem is most sites (Facebook for example) use multiple SSL domains for things like images and other resources. So I'll get a page that half loads until I go an "proceed anyway" on each of the problem domains.
