I used to meticulously organize my Firefox bookmarks into different folders and subfolders. A couple of years ago, a friend of mine showed me the Tab groups features (since then deprecated, but lives on as an extension), and I don't think I have bookmarked a site since then. I disable loading until click, and the browser shows me the entire set of groups if I close it and reopen it.
