Over the years I have saved many bookmarks in Firefox in various folders for interesting, useful or just frequently used websites.

Now I've recently moved a lot of stuff to more private (foss/selfhosted) alternative and I'm considering moving browsers too. Since the bookmarks are so integrated into the browser I was wondering what you guys do/recommend in order to keep a bit more freedom.

One option I could think of would be to write them into a Markdown doc and to sync it with all the other notes I keep but that's a bit inconvenient - there's got to be a nicer way that doesn't send every action to a browser corpo, right?
