Scrolling by pressing bottom arrow in scrollbar causes strange behaviors

[mikesmithv]

Binary package hint: firefox-3.0

On the site http://slashdot.org/ scroll by clicking repeatedly on the down-arrow of the vertical scrollbar. Every day somewhere around the middle it will jump several articles with one click. It seems to be related to certain ad's going by but I'm not sure of that.

Update: This bug cannot be reproduced by scrolling quickly. It only seems to happen when scrolling and pausing, at the speed of reading the web page. Also, it seems to be a problem in Firefox computing the size of the web page. When this happens the scrollbar thumb is approaching the bottom when the jump happens. Then after the jump the thumb pops up to the upper part of the scrollbar and reduces in size as if the visible area is now a smaller percentage of the total page.

Another related problem happens if you press the same down-arrow button and leave it pressed for continuous scrolling. As the web page scrolls the window will suddenly dim and a message appears saying "Firehose Paused due to inactivity". These problems don't happen in Windows XP using the same version of Firefox.

I don't think this is Ubuntu specific, I am having the same behavior on MacOS 10.5.6 using Firefox 3.0.10.
