Events are *not fired* in the following situations: - page up/down - arrow up/down left/right - home/end - scrollwheel Reproducible: Always Steps to Reproduce: 1. Create a page with lots o' content and an onscroll listener that alerts (or notifies you somehow) 2. Scroll as many ways as you know how. 3. Notice that you only get the event fired when you are playing with the scrollbar directly. Expected Results: You'd expect the event to be fired whenever you scroll a page regardless of the means of scrolling. I think that firing the event on scrollwheel movement is especially critical as it seems to be the way that folks use to scroll through content these days.
Please test with a nightly trunk build. This should be fixed in current trunk builds: http://ftp.scarlet.be/pub/mozilla.org/firefox/nightly/latest-trunk/
