Before the update of Firefox for Android, when I viewed 'Top Sites' on my home page, I could see six thumbnails that I can pin and a further list of sites from my history in order of how often I've visited. Now, I get eight pinnable icons, and either a list of most recently visited sites from history, recently bookmarked pages, or 'recommended' pages. I cannot find how to get the list of most frequently-visited sites to display any more.
