In *chrome or *iehta mode, navigate to a site with an invalid SSL certificate. You'll get a pop-up warning from the browser.
This will happen to any browser that isn't configured to use the Selenium proxy, because trustAllSSLCertificates is currently just a proxy setting. Ideally we'd configure all other browsers to ignore SSL certificates somehow (assuming that's even possible!).
Can we have some clarification on what it means to "use the proxy"? Does this mean proxyInjectionMode, or providing the proxyHost / proxyPort settings? Or something else?
