True in every browser I've tried far. I also had two separate blogchain tabs hard-hang and they had to be killed. I'm not sure I'm ready for all of this mindboggling innovation in UX. :)
Same on Safari mobile.
press the back button longer, until you get a popup, then u can jump 2 steps back in the history at once.
but of course it sucks, that a single press in not enough...
