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 :)

Schönes Addon! So kann man schnell simple, schicke Notizen erstellen, einfach während des Surfens. Kann mich nicht beklagen. Mozilla könnte das Addon aber ruhig mal wieder updaten!

Nice. Please change the colour of the icon in the sidebar, as it currently blends with the Dark theme background. Ability to create folders for notes would be great. Thank you.

Honestly really like it for quick notes. Can sync it up to phone as well which is handy. Plain and simple.
