Facebook and Twitter are owned by companies and have a single point of failure. Many users won't use sites that only provide these as a login method for various reasons (they don't like social media, etc). OpenID seems to be difficult for non-technical users to grasp. They don't understand what it is or the fact that they probably already have it. Even technical users can have issues (what OpenID login did I use, which of my multiple current Google accounts are being used, etc). BrowserID is being advertised as the easier alternative for users and developers I think. BrowserID is not Firefox specific. The JavaScript shim works across a number of browsers.
