Was really happy to find this since scrollyfox doesn't work anymore. It does work on multiple tabs which is great, but dosn't work once the tab has been refreshed.

UPDATE: I would be happy to give you as much feedback as possible because this is an addon I really would like to see working well. I have a computer that I use just for displaying websites that I want to monitor: Craigslist, twitter, Feedly (a news aggregate site) and then a basic weather page that I don't need scrolling. This monitor is separate from my main computer and I would rather not have to ever click over and mess with it. I just want it to cycle through these four tabs which auto refresh and then scroll down and when the reach the bottom scroll back up . I used to use 2 addons to do this one is tab rotator, and the other was scrolly fox, which quit working in the last Firefox upgrade. Your addon is the closest to scrolly fox I've found. I found the settings you mentioned and it does seem to be working now on refresh but, at least on craigslist, it 's not scrolling back up when it reaches the bottom. It seems like it does slow down the browser quite a bit, may be if there was a way to only have the active tab scrolling that would help. Please let me know what other feedback I can provide because I would really love to help make this addon great!

UPDATE2: For some reason it stopped working for feedly.com, still won't scroll back up when it reaches the bottom of a craigslist page
