I have been autoupdated to firefox quantum. All my bookmarks seem to have disappeared. Right-click Library-> customise opens the customise window and I can add the bookmark button to the overflow menu (Why not the main menu, it is one of the buttons I use most) but all of my bookmarks show up individually, not in sub-folders (as I had them organised before quantum). If I try and organise the bookmarks, I can see my folders, and I can make new ones and copy rthe bookmarks over, but they still appear as individual entries on the bookmarks menu (which is still hidden in the overflow menu). How do I get my bookmark organisation back please? Stephen
