I have the smooth scroll add-on working just fine to enable good smooth scrolling, so this is not the issue. The issue is with Flickr and their script when it reloads/adds the next set of images when you reach the end and it say (paraphrased) "loading more images." After they are downloaded and appended to the cache, Firefox jumps back up to top the image Que and I have to grab the scroll slider and hold it, scroll down holding it, and keep holding it to reach the end of this first page of images, as which time I see a button to go to next page.

Is it possible someone can look at the Flickr script and how Firefox is responding, and fix this? I'm thinking a modified branch code for Firefox with a "scroll cache" that can read ahead and feed Firefox independently from direct Flickr feed, and this cache set aside to it's own hard drive space on my computer just for photo streams can be created as an add-on Flickr module with additional code added to Firefox just for this add-on? Also, the benefit could be that it simply become an add-on for local cache management for photo streams and a "buffer augmentation" add-on?
