It works well, it syncs with my Android phone well, and it has makdown support! Downside: most of the apps to take notes allow you to classify notes by tags, folders... it would be nice to have tags, and be able to filter by them. Also the lack of a search future makes it not an option for large number of notes.

mazilla i love you

Well, since it was released in the Firefox's Pilot Project, I started to use this tool and, sincerely, I can't imagine my browser without this add-on anymore, but there's something I think it still missing.

It would be awesome if we could organize our notes in separate folders.

Please don't abandon this feature. It would be great if we could have a quick syncable clipboard too.

Same here. When using app an Android (Fairphone 3) I get my texts duplicated separated by
"**** Auf diesem Computer: ****"
(I would translate it as "changed on this computer:" - but I did not change them on the computer but changed them in android app during beeing offline.

Very useful

Great extension, it should be installed by default! 很棒的扩展，应该默认安装！

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?

This is very limited and requires that you have memorised markdown. OK, that isn't too difficult and if that was the onlt problem I'd be happy with it and give it 4 stars.
My real problem with this system is that the Android app requires that I go through 2-factor authentication *every time* I synchronise. Therefore it is not possible to make a quick note or refer quickly to a note made on another platform. I do not understand this decision, the Firefox extension doesn't do this and it is unnecessary - if you want to offer this as an *option* for the paranoid and those that can't make their phone as a whole secure, fine, but please don't force it on everyone all the time.

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 ;-)

It would be great adding multi-notepad and/or tree style notes

easy to use and sync's across :)
