There's absolutely no reason why backing up would need to be manual if you utilized a third-party cloud storage API. Perfect example: you can sync Broken Sword 2 save files between platforms via Dropbox, automatically, even on iOS. If it can happen for a game, why not a bookmarks system? But to be honest, why not just sync via a browser extension? Plenty of browser extensions already use Mozilla/Firefox or Google accounts to sync their storage. I live in the UK, I've got a lot more to be angry about than an HN comment, and if I'm in pain, it's because I've got Ehlers-Danlos syndrome. FYI, blockchain is a terrible idea for bookmarks because it is immutable. If someone does figure out decrypting it, that's a lot of potentially very compromising information in the public domain, especially on bookmarks that include your username and additional info in their title or description.
