I just fixed this myself inadvertently. I tried installing the autopackage of version 0.7 from the developer's site, which installed fine, but actually created another scrollbar drawing bug. The one I describe here was fixed, though, by a simple Firefox profile change. Since 0.7 had another annoying bug, I uninstalled it and reverted back to 0.6... only to find that things are now working perfectly!
Ignoring my little story above, all you have to do is add this stuff to your userContent.css in ~/.mozilla/firefox/[random- string].default/chrome/: # The following four lines were added by KDE scrollbarbutton[sbattr="scrollbar-up-top"] { display: -moz-box !important; } scrollbarbutton[sbattr="scrollbar-down-top"] { display: none !important; } scrollbarbutton[sbattr="scrollbar-up-bottom"] { display: -moz-box !important; } scrollbarbutton[sbattr="scrollbar-down-bottom"] { display: -moz-box !important; } You can customize these lines for your KDE style, but that will fix it to work with the default on Kubuntu (Lipstik).
