Firefox must have realized that their UI for handling "top sites" was bad. In ESR v60.7, the Tiles/topSites block has a menu where the first entry is "+ Add Top Site". This was missing before. In fact, this problem was not directly mine, it was a request from my parents. I made my parents (nearly 70 years old) use Firefox. After an upgrade of their FF, they lost their usual homepage. In empty tabs their custom links were replaced by the dynamical list of their most visited sites. At the time of change, most tiles were not even relevant because their recent activity was not representative. They were annoyed, tried to fix it, and failed. There was no contextual help, and searching technical info is hard for non technical persons, especially if they don't understand English. So my parents called me for help. On my next visit to them, I tried to do it myself, but did not manage to guess how it worked. DDG helped. After this episode, I wondered if FF was the right browser for them. It seems that Chromium's UI is more stable, and that is important for ageing people.
