Private Notes gives you safe and encrypted place for your Top Secret notes!

  • Encrypted notes - all your notes are always stored encrypted!
  • End to End encryption - all transferred data are again encrypted thanks to Firefox Sync
  • No need to create additional account - Firefox Sync will handle everything

  • Auto-lock - will help you keep your notes locked when you leave your PC
  • No Ads!

Auto Highlight

Download for:

Auto Highlight will automatically highlight defined words on defined pages.


Sometimes the page is just not designed well and the information you are looking for is not visible enough.

Common use-cases:
  • highlight metadata like: 1080p, HDR, UHD
  • hide words (font-size: 0) you can't stand anymore (covid-19? :D)
  • make that "download" link bigger

Movie Meter

Download for:

Movie Meter shows you movie rating and it's popularity on many movie-related pages. For TV Shows it finds information about Next / Previous episode.

  • movie rating and popularity
  • next / previous episode date
  • additional movie information
  • auto-hide when video detected
  • active development!
  • No Ads!

Warning: while it works perfect for most movies, it's not 100% - sometimes movie is not detected or even wrong movie is found. I will try to improve this over time.

Send Note to Device

Download for:

Send Note to Device allows you to send text messages (notes) between your browsers.

Currently the add-on uses Firefox Sync / Chrome Sync engine to transfer messages - this mean that you cannot send message from Firefox to Chrome.

Lack of Firefox Sync for add-ons on Android also means that there will be no Android version until I implement new synchronization using my own Cloud server.

Save my Password

Download for:

Save my Password will allow you to force Firefox to store your password on any page.

Why? Some login pages are designed in a way that your credentials are not stored by Firefox and you have to type them yourself every time.

Fast Firefox Send

Download for:

Fast Firefox Send is unofficial extension for the "Firefox Send" service to make it faster and better!

  • upload files directly from any page - using context menu
  • remember last expiration limits - "Expires after X download or Y days"
  • list of Uploaded files - history of last 100 uploaded files
  • access your uploads anywhere - Firefox Sync will sync your list of uploaded files
  • End to End encryption - both "Firefox Send" and "Firefox Sync" are encrypted!
  • No Ads!
