No, it's neither of those things, but I did notice something fundamental today when loading the extension in a VM installation: it looks radically different than what I've been seeing. That is, Options comes up in its regular (meaning what I've seen in other browsers) tabbed UI.
But in my main install, it doesn't. Instead, all options come up on one page. It's the same page that you can see for an instant before the tabbed UI loads, especially if you've just run the browser fresh. Maybe it's CSS failing, I'm not sure.http://screencast.com/t/AqrZgzm1q
I have seen some other reports about this in the Feedback tool, so it's not just unlucky me.
