On Mac OS X, three-fingers gestures (top-to-bottom or bottom-to-top) used to scroll to the bottom or top of the document. I am really used to it and find it much more important to my daily browsing life than the new settings, showing or hiding Panorama. I restored the previous settings with the following:

  • set browser.gesture.swipe.down preference to cmd_scrollBottom
  • set browser.gesture.swipe.up preference to cmd_scrollTop
