Is there any option in a webbrowser (IE, Firefox or Chrome) to allow scrolling up to one screenful past the end pf the page? When reading a long page of text and pressing PAGE-DOWN to scroll to the next page, the text at the bottom of the browser window is scrolled to the top of the window (with an approximate overlap of two lines). When scrolling to the last half- or quarter-screen, the bottom is scrolled to somewhere in the middle of the browser window (based on how long the remainder of the document is), forcing me to search for my place.
A plugin or addon that would allow toggling this behavior would be even better.
Something like the ScrollPastEOF plugin for Notepad++, but for web browsers.
