xBrowserSync has completely replaced all bookmark managers for me. No more hunting through extensive folder trees (what a mess that was!). When adding bookmarks, I just manually add a couple tags and be done with it. With xBS, bookmarks are accessed mainly through a simple tag/keyword search.

Bonus: I'm no longer tethered to any particular browser's sync ecosystem. BitWarden has my passwords and xBrowserSync has my bookmarks. I can browser hop on all my devices!

Double bonus: Open source and you can self-host.
