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).

BACKUP YOUR BOOKMARKS! I installed this, moved bookmarks into the private bookmarks area, then locked it. Came back the next day and unlocked it only to find all the private bookmarks EMPTY!

I had a backup, but if I hadn't all my private bookmarks would have been lost!

I use Firefox sync, and I read the description before installing and using it too.

The github issue tracker is full of issues and bugs. My advice, avoid, look elsewhere.

DO NOT USE!! No longer updated. It will make private bookmarks visible in synced devices without requiring a password.

Randomly saves bookmarks normally instead of privately

Was amazing but password no longer works! Edit: Lost my password AGAIN ~2 weeks later with my new bookmarks this is stupid! For some reason this time it seems to be because my previous password was under 8 characters, now it's asking for over 8 for some reason. Please fix this atrocity. It also asks for a number now. It's local you morons

I have either forgotten my password or it is no longer working. Needs to add some kind of password recovery system. Why not let it have email as a means of recovery?

decryption process taking more time which is not expected for a bunch of bookmarks.

Lost encrypted bookmarks, extension not updated anymore, dont use

Does what it says on the label :)
