Dark Mode Is Needed ...

La uso mucho, pero tuve que formatear la PC y perd{i todas las notas

It does what it says, but note that the sync no longer exists, despite what the welcome page says.
Apparently, sync is no longer available as the extension is no longer maintained. (Search "Firefox Notes status")

Great add-on. Just wish sync feature still worked

Sehr rudimentär.

This Add-On corrupted my Bookmarks. I highly recommend 'NOT' to use it. You should also note that it was last updated 2 years ago (Sep 17, 2020).

Ok

needs to be developed more, if there was more options and a way to import the html files back in then this would be 10 stars.

I like having the convenience of the sidebar to take notes while on a website. However, it is TREMENDOUSLY LAGGY. Not sure why, given it is a very bare-bones extension. Using any kind of formatting (Title/Heading fonts, bolding, using italics, etc.) seems to be the main cause of lag, even if you aren't extensively using those tools. Plus, when I click off of a note onto a webpage, then back onto the note in a specific place, the text cursor instead jumps to where it last was before I clicked off. I find this rather irritating, especially when doing lots of copy/pasting.

great extension. I would like Mozzila to continue its development.

Dark theme needs some tune up (tested on Windows): some fields remain light. Also it would be great to have an option to change fonts. :)
And yes, the other reviewers are right, search is a must!

Very handy. I only wish i could save different notes for different sites and have each pop up automatically.

best f**** app ever. the only way to take notes. seriously.

It seems to be a single page of notes with no way to add a note by page, website or global. No way to search or filter the notes in any way. A bit useless really.
