"lets you take notes on web pages."

No it does not... The notes are not related to the webpages at all... It's just a notes sidebar.

Can't input chinese characters.

Deleted all my notes without reason.

Please optimize this extension for Firefox Android

this one day out of blue delete all my notes even not i had cleared my history or made anything unusual. Besides delete thoroughly my info it's impossible open on android

Obviously, synchronization is not perfect. If you delete the extension and install it, it'll be reset. Anyway.

No tiene diccionario español y las notas están subrayadas como mal escritas

J ai changé de téléphone, un transfert de toutes les données a été effectué .quand j ai ouvert notes sur le nouveau téléphone c etait vide j ai perdu toutes mes infos et je ne sais pas du tout comment les récupérer

Loved this app for it's simplicity. Then I had to reinstall my Firefox and all my content was gone. I lost a TON of important stuff. Thoroughly disappointed.

This is great feature in browser. No need to juggle between browser and other tools to make notes.
Edge has something in form of collection. which is better but I liked simplicity of notes in Firefox. But one day I rebooted my PC and all my notes disappeared. I have no clue why that happened. I'm using 78esr so there was no major upgrade happened to my browser.

I see other people having similar complains but seems developers have no clue or are not interested in helping. I lost some important information in those notes. :(

I've resetted my PC today and it seems that I lost all of my notes. Thanks Mozilla.

Fatal por discontinuarlo. Flaco favor a los principios de Mozilla

A great idea, but poorly executed. Lots of bugs and performance issues. This morning it won't open at all.

I lost all my notes and I don't know why :/
In which folder all the notes are being stored?

Looping between verify your account and reconnect...

I thought notes were associated or linked to the web page where they were taken, as it should. What's the goal of a notebook app in a browser if the notes are not related to the pages?

La synchronisation entre appli smartphone et extension navigateur sur PC est aléatoire.
Accumulation d'historique "sur cet ordinateur".
De plus pour se connecter il faut entrer un code de sécurité transmis par mail même après entrée mot de passe. C'est très lourd pour un fonctionnement erratique.
J'utilise des mots de passe sécurisés, et il me faudrait vraiment une option pour supprimer cette connexion à deux étages totalement anti ergonomique sur un smartphone.
Soyez la solution pas le problème ;-)

Have been using this for months now and noticed that it was adding ****Notes on this computer**** or something similar to some of my notes so many times that it would lag Firefox. Could not stop this behaviour between phone and computer so deleted notes on phone and it synced straight away to desktop and I've lost everything. Am shattered...

Not working for FF 73.0.1 on Win10. Notes sidebar appears, but there is no way to type in anything. Don't see any "+ New Note" button or any other button. Just an empty side pane with apparently no text box in it.

Worked just great until one day it didn't. I got a "Notes Storage Full" error and then one of my longer notes that I had been adding to for a couple months wouldn't open anymore. I almost lost it all except I was patient and gave it a minute to open. Once open it was very sluggish but I was eventually able to copy the text out. It seemed to have trouble syncing because my note text was duplicated several times over with the note *** On this computer: *** appearing several times, making the note 10x longer than it should have. Will never use again.

Nicht genug Speicherplatz ist die Fehlermeldung. Hab das Addon schon deinstalliert und neuinstalliert.

Die Anmeldung ist nicht mehr möglich, weder unter Ubuntu noch unter Windows :-(
