After Firefox updated to 65.0 it became terrible to use bookmarks. There are 3 ways to access them (sidebar, library->bookmarks, bookmarks item on toolbar), but all of them are inconvenient and time consuming. What was better in previous version? You only need to CTRL+B and choose one of the recent bookmarks which appeared on sidebar. But now to access recent bookmarks the shortest way is to go to library->bookmarks, which is more time-consuming. Another way to access, e.g. 15th recently bookmarked bookmark, is to go CTRL+B, expand "Other Bookmarks", and scroll whole list of bookmarks down. So why this list isn't sorted upside down by default to access recent bookmarks faster?
