Bookmarks are not a safe way to store links, as I have learned. Every URL can only be present in a single bookmark, and an addon can mess it all up if it decides to create new bookmarks for links that you have already bookmarked. It’s location (the bookmark directory) and tags are lost, and if the addon decides to delete the bookmark that it has made, the link itself is lost too.
