One of the things I liked about Firefox is the ability to select from about 20 recently visited sites, displayed as a grid of easily recognized graphic thumbnails, when I opened a new tab. By <Ctl -> I could shrink the thumbnails and display more recently visited pages. Yesterday's patch has changed this facility to a single line of six thumbnails under the heading "Top Sites" and a bunch of distracting larger thumbnails under the titles of "Recommended By Pocket" and "Highlights". This doesn't bother me, there's a settings gear wheel where I can turn off everything but "Search" and "Top Sites". The problem is that I'm still only looking at 6 thumbnails of recently visited sites. I want to be able to select from a larger array of them. How do I get the number of thumbnail references under "Top Sites" that I had two days ago?
