User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040206 Firefox/0.8 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040206 Firefox/0.8 In the page at http://www.epa.gov/OWOW/NPS/MMGI/Chapter4/ch4-5b.html, and many others but not all, Pageup/Pagedown fail to operate correctly. Exact results are erratic, but typically Pagedown will move down one or two screens, then may return to the top, near the top, or just jump down and then back to the previous position. Pageup suffers from similar behavior. The same page works normally in Mozilla 1.7a on the same computer. I have some extensions installed, including Adblock and the Flash blocker, but even with those turned off I got the same behavior. Much as I like Firefox, which is my default browser, this behavior is really difficult to tolerate. Unfortunatly, I have not discovered what features of a page are associated with this behavior. I am reporting this for Firefox 0.8 on Windows 2000, but it was present in at least some predecessors. It is present in all three Firefox installations I have on three different computers. Reproducible: Always Steps to Reproduce: 1. Load problem page, such as the URL given above. 2. Click in the content area to make sure that the Pagedown keystroke will be registered. 3. Press the Pagedown key (either the one on the numeric keypad or the other one). Repeat Pagedown until either you get to the bottom of the page or you notice that the page does not move down one page as required. You may find that the exact (mis)behavior changes as you continue to press Pagedown. Pageup displays similar incorrect functioning. Actual Results: For the first three Pagedown keystrokes, the page moved normally. On the fourth, it jumped several pages in the wrong direction, but not all the way to the top. After this, for each Pagedown keystsroke, the page jumped down and immediately returned the the same location it had before the keypress. Even after I scolled down several screens by clicking in the scrollbar, the page returned the the same place it had stuck on before when I again pressed Pagedown. Expected Results: The page should have jumped down towards the bottom one screen at a time.
