Private Notes od Juraj Mäsiar

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

Limitations of Firefox Sync engine:

• No Android! Firefox Sync cannot synchronize addons data on Android :(
• Firefox Sync can handle only 100KB of data - so you can't store huge notes. However thanks to build in compression, you should be able to store more than 100,000 characters of text.
• Single note only 8KB size limit - each note can have only up to 8,000 characters - again thanks to compression this should be more.
• Slow synchronization - sometimes it takes several minutes to synchronize your new notes to / from the cloud. You can trigger sync. manually from your account toolbar menu.
