Add-on summary

Private Notes allows you to write password-protected, fully encrypted notes. Your notes can be synchronized with encrypted (again!) Firefox Sync. engine with other devices. Ideal for storing the most sensitive information, like Recovery codes, Wi-Fi passwords, server configs, etc...

Privacy and permissions:

  • There are no permissions - this addon can't make any remote requests or submit any data!
  • All data are always encrypted and then synchronized by Firefox build-in End-to-End encrypted "Firefox Sync" engine (yes, data are double encrypted!).
  • Your password is NOT stored at all. It's hashed using advanced PBKDF2 function with 100k iterations and strong salt.
  • Unlocked notes and decryption keys are never stored on drive - they stay in the system RAM memory (not accessible by any other app and cleared when browser is closed).
  • Even if someone gains physical access to your PC, he won't be able to access your notes nor password. This is one of the safest place ever created!

Top features:

  • Encrypted notes - all your notes are always stored encrypted!
  • Auto-lock - will help you keep your notes locked when you leave your PC
  • Automatic backups - each device creates encrypted local backups of your notes. Plus Firefox Sync engine keeps encrypted backup in Firefox cloud.
  • End to End encryption - all transferred data are again encrypted thanks to Firefox Sync between your Firefox browsers.
  • No need to create additional account - Firefox Sync will handle everything
  • Advanced Text Editor - supports many advanced text features
  • Code highlight for many popular languages and configs
  • Compression - all notes are compressed to save space

To synchronize your encrypted notes between devices:

  • enable Firefox Sync feature - just login to your Firefox account using toolbar icon
  • enable "Add-ons" synchronization - in the Firefox Options page ("about:preferences#sync") on the "Sync" tab check "Add-ons" checkbox

I like how it works and looks, except it is missing: 1) search in notes and 2) categorizing notes into expandable (sub)folders + being able to move items between these.
