The only browser bookmark I use is:

    javascript:window.prompt("Title + URL:",document.title+"\n"+document.URL);

Which when clicked, opens an alert with 2 lines like this:

    Bookmarks.txt is a concept of keeping URLs in plain text files | Hacker News
    https://news.ycombinator.com/item?id=45047572

I then paste this into my bookmarks.txt and have a simple text editor script to perform fuzzy searching on it and open a web browser tab with the found URL.
