I have a problem when I read a specific webpage and firefox jumps to the end of the webpage. This happens with one specific webpage, a Swiss newspaper: call www.nzz.ch - Now, select one of the articles but in the following way: do a right-click on the title of the article and select "open in new tab". (This is important: it does not happen if you left click on the article and open it in the actual tab.) Now you have the article in a new tab, you begin reading it and slowly scroll down using the mouse wheel. But then, with the slightest scroll back (upwards), firefox will jump to the end of the web page. All you can do is go back (ctl+upward arrow) and look for the place where you have been. Once this has happened, firefox will no longer scroll to the end of the page, you can scroll up and down, and everything works fine. But if you close the tab and open this or another article again with right-click, open in new tab, you have the insane effect again. I have no idea how I could analyze this myself and am thankful for help.
