I have a 74 page paper from the ACM open in the FF addon (FF nightly), and if I happen to mouse over the sidebar such that it opens, generating the previews for all 74 pages slows FF to a standstill for at least a minute. It's hard to tell who is at fault here, but I think that the best solution is to generate previews as needed - if I don't scroll the list (and in fact close the sidebar), there shouldn't be any need to generate any previews that aren't in view.
