Thank you. It is very helpful but how do I export my notes?

Nice....

Excelente, solo falta que sincronicé en la cuenta de mozila y listo

I like this app. It's simple. Visually it's somewhat drab. If it could have some colour or be able to have skins attached it might work like a happy face.

Simple Notes is the only sidebar note-taking extension at the moment that can serve as a replacement for Quick Note, killed off by FF57. Thank you very much.

It seems to work all right. My only criticism is about the upper input box that retains the title of the individual notes. It wastes space, especially that it comes with a pre-determined minimum height. Apart from the 'add' and 'remove' buttons, the area over it also remains unused. I would welcome a change of interface with tabs on top.

Needs more work. It does not have an icon so you will find it in the Sidebars button. The bottom box is for typing in notes, I guess, but
the entries in the top box show up and interfere with the bottom box.
I guess that is so you can edit the top box entries. It's a bit of a mess.
I was looking for something like the old Quick Notes.

Very limited functions.
