DSSID has been tested in FF, Chrome, Safari and Opera. It doesn't depend on certificates, so deleting your root CA's shouldn't make a difference. Google "HTML5 local storage" for more info on localStorage and sessionStorage.
When I click "Login with DSSID", the page says nothing except "Welcome to DSSID". No login box, button, or anything. Of course, it's not your fault, because when I do a View Source, I see all those things. They just don't appear to me visually.
This is happening on two different Firefox browsers on two different Linux machines. It must be a problem with settings or a plugin. I'll try it on a brand new Linux machine with a fresh install of FF and let you know.
Of course it's my fault :-) Failing silently is never acceptable under any circumstances.
That said, a silent failure is pretty weird. It can happen if you have Javascript disabled (are you running noscript?), but there's a check for that on the demo page. I just added an explicit check on the DSSID page, so please try it again.
I'm pretty sure the problem is actually related to my deletion of all root CAs. Why? Because there's a red exclamation mark over the lock icon at bottom right of window, and when I hover it says "Warning: Contains unauthenticated content."
I already force-accepted the dswi.net certificate as a specific exception when I first played with DSWI yesterday. I would think that acceptance should apply to the JS content as well. But apparently not. So I'm poking around in my FF settings to see how I can trust your certificate even more than I already have -- yet without installing Comodo's root CA certificate.
It's all my fault, because of my bold yet insane experiment in distrusting all root CAs.
