Apparently Firefox Notes was shut down in September 2020.

супер удобная штучка

pretty simple and pretty good

The advertised "Sync" feature doesn't work. It was removed at some point in time.
So, at the moment Firefox has not notes or file sharing add-on or functionality.
Otherwise, if you use just your PC, it's a note taking sidebar extension, as advertised.
There is no way to access your notes on mobile phone.

Hasn't been updated in over five years and can no longer be installed on Android. Clearly not supported anymore, which is a shame as it the sync capability was a great point of difference against Android.

Just added this on - love it already! If there could be some kind of pop up or warning when you go to delete a note -- along the lines of "Are you sure you want to delete this note? This action cannot be undone" -- that would be super helpful. Thanks!

Needs hyperlink support.

Bring back sync!

Le mode sombre est bogué, il reste toujours une barre d'outils claire en bas du panneau de l'extension :(. Ça fait mal aux yeux.


The dark mode is bogged, there is always a clear toolbar at the bottom of the extension panel :(. It hurts the eyes.

This is nice, but I wish it respected the theme colors. My entire browser is a particular color and other sidebar addons are that color are well. This one addon does not respect my theme and is pure white.
