Very simple extension. Works well for me on Firefox 135.0 as of February 2025. It would be nice to be able to customize the location of the Private Bookmarks folder (mainly so the "Other Bookmarks" folder doesn't get involved), but that's super minor.

great app

Невероятно! Перфектно, ако искаш да скриеш някой неща.

Still working fine. Even after 5 years. Thanks to dev.

Private Bookmarks enables a special password-protected bookmark folder. Your private bookmarks are encrypted with your chosen password. This is not an online service, and you are in control of what data leaves your machine (if at all).
