Feeds not scrolling properly in all feeds list.#331

Again, with Latest stable Firefox and NVDA 2015.1, when going down through the list of feeds in expanded mode, the page will not display all the feeds in my all feeds list. This is probably expected behavior, but when I reach the bottom of the list, I presume it should automatically load the next batch of articles, as there is no visible control at the bottom of the page to do so. I thought this would be what the page down button at the top did, but I have had inconsistent at best results. I've had to refresh the page with the mark as read when scrolling option checked. This produces the next batch of feeds, but because for whatever reason I come in at the bottom of the page, all the articles are marked as read already, which is a minor annoyance.
