Apparently Firefox updated overnight and now my New Tab Page, which had a ton of tiles on it that I'd pinned over the years is now completely blank, no tiles, no nothing (except the Firefox logo). If there were at least some blank tiles, I'd have something to work with, but when I say blank, that's exactly what I mean. Is there any way to get back the tiles I had? Because none of the pages I've opened or searched so far has created a tile on the page. Thanks.
