I used to be a bookmarks hoarder. I would create folders for the bookmarks and organize them by category and activity, but about a year or two ago I set up an instance of Karakeep and I have honestly not looked at my Firefox bookmarks once since I did that. that. Whenever I want to save something I just save it to Karakeep which automatically tags it, pulls down an archive of it and also generates a preview of the page. It has made my bookmarks so much more useful than just having a title and a URL that the Firefox bookmarks window has.
