[Pharo-project] Noobie Browser question

The Browser in Pharo Core and Pharo One-Click doesn't appear to have the features described in the Pharo By Example book in chapter 6. In particular, there is no History bar at the top. Clicking on the gray lozenge at the upper right of the browser window gives me the option of selecting the Browser or OBSystemBrowserAdaptor, neither of which seems to have the features shown in the book. Is there somewhere I can get the OmniBrowser described in the book, or has it been replaced with what appears to be a less-functional version? Thanks, TF
