It does what it says but seems useless because it is not different from manually clicking in the side bar or using Page Down key of the keyboard. I was looking for an automatic page down add on that will pull the page down at certain time intervals like every one minute. In this case, it should also pull down only specified number of times. I use an auto reload add on but the website for which I use it reloads the page always going back to the top of the page. It requires manually pulling it down after every reload. I wanted to combine these two add-ons so when the webpage reloads automatically, it also goes back and down to the position where I had set it.
