For me, doesn't do what it says it does. Tabs are not suspended, they are completely discarded. There are no distinguishing features between active and discarded tabs (icon is unchanged, there is no dot). Switching to the tab, it starts blank and has to completely reload itself from the Internet. If I were trying to continue reading on an airplane, lets say, I would be out of luck. Maybe that is what it is supposed to do but that is not the impression I got from the description.
