Функции свои выполняет. Но синхронизации уж слишком много - стоит элементарно установить курсор посреди текста (т.е. никаких изменений самого текста), и уже начинается синхронизация, напечатал пару букв - синхронизация. На стареньком ноуте что-то записать - сплошная нервотрёпка. Гораздо лучше было бы, если бы синхронизация была не автоматической, а была реализована, например, в виде кнопки "Сохранить" - напечатал, что надо, и сохранил (синхронизировал), когда надо.

sync feature is really buggy sometimes it sync notes and sometimes it doesn't and needs search feature

A nice and simple addon. Missing search functionality. How am I supposed to find my past notes?

It works good and does it what is says it does. ;)
Using it on Windows 10 and a Android Phone.
Picture support and a stand-alone app for windows (like the sticky notes app) would be awesome.
I would like to see my notes on my second screen all the time.

But this is Mozilla, so it will come a long way... keep it up!

Fajna apka. Jeszcze nie wiem jak skopiować tekst aby zachować układ z notatnika dla Win ale pewnie się niedługo dowiem.

Everything is excellent, but picture support would be so so useful

This is the space Firefox should start going after. Utility apps for people leaving google. Please expand on this more, there is so much potential.

A ideia é muito boa, entretanto, sem opção de pesquisa complica o uso.

Me gustaria que las notas se separarán del modo normal y el modo privado

Write text notes and sync with all your devices - cool stuff. For 5 stars, please add: note tags, images to notes.

It is a very useful tool for me. I've seen a few times where it said it was synced - but, when I came to another computer, latest edit/update was not synced. Yesterday, like a few others. It started to become so slow that it is best described as unusable.

Please add ability to hide Notes after second click on extension bar. Now only open work.
