Pro:
• FOSS
• Useful declared functionality.

Cons:
• The extension settings are reset periodically (the default settings do not suit me).
• The account is periodically logged out (used to synchronize settings between extension instances on different computers or to restore them after reinstalling the browser).

2025-08: At some point, Mozilla Firefox stopped launching in normal mode, but only in Troubleshoot Mode. While in Troubleshoot Mode, I disabled all extensions, then started enabling them one by one, restarting the browser afterwards. When I got to the Notefox extension, in which I had quite a lot of notes by that time (a hundred or more), enabling it almost immediately leads to an irreversible hang of the browser. I am forced to kill the browser process, launch it again, enable the extension - and again get an unresponsive browser window.
I had to stop using the extension.

So far the only extension in this kind that really works. For me, it is a life saver.
The developer is responsive.

Works well as described. Wish there will be tagging/label option and more optional/customisable colours theme than in the future.

Looks like the only notes extension that really works! Please, keep up the good work.

I really would have loved this as it seems so well put together, clean, and thought out except for on flaw. Yes, it does create notes for a page, however those notes do not show up on the page at all. In fact there is nothing to let make you aware that you ever did create a note on a page. Instead you have to click on the extension and then you will see your note. So, unless you remember you've made a notation to a page somewhere, or refer to notes made in the past within the extension itself and then revisit a page from there, you have no idea if you've done so. Its a bit unrealistic to expect people to remember they've created notes on websites/pages should they go back to them if there is no visible sign that you've done ever done so.

Aside from that major flaw, the only other aspect I would add would be to allow for the add-on to be accessed through the contextual menu rather than having to click on a pinned icon in the toolbar.

In my Ubuntu + iBus + Firefox, Korean input is broken and only English can be typed, but this add-on is really practical. I recommend it!

So this is nice! But Can we have the option in the settings to move the notes to the sidebar so that it can stay open while we are browsing?

Just what I wanted
Very useful for certain websites that I use
The author very quickly assisted with a query that I had and a few minutes experimenting
I was able to fulfil my requirements - automatically open a previously written note
Thanks Saverio.

It has some keyboard focus issues sometimes (cursor keeps going to the start of the editor while you type), but the ability to associate the note with e.g. certain subdirectory trees of a site makes it perfect to keep notes between all pages in certain part of the site.

I absolutely love this add-on. Extremely well made. It would be neat if I could edit the text or UI color from the add-on toolbar. Awesome.

10/6 Thanks for the reply. I found a color I like. I keep having this issue though where the window flickers and it's not word-wrapping the text.

Nach diesem Tool hatte ich lange Zeit Ausschau gehalten. Ein Notizzettel der sich auf einer bestimmten Website einblendet, zu der ich mir einen Hinweis erstellt hatte. Top :)

my only feedback would be to allow different full-color sticky notes or drop-down menu notes.

For instance:
- For stickies: instead of the "tag" being cyan, the whole note is cyan
- For drop-down, when selecting cyan, the orange border/frame changes to cyan

Nice one. However when taking notes on websites that play video/audio material addon's window shuts down or a cursor of the fixed window resets to the initial position, which makes taking notes on youtube videos unconvenient.

Just did a Firefox refresh, not as traumatic as I thought it would be and looked for addons. When I found this addon I was delighted. It fills all my requirements and answers the other problems similar addons haven't addressed. I hope you enjoyed the coffee.

Thank you, finally a notes extension that works as it should! All that's missing is sync and it would be perfect

This is an addon that a lot more users would find useful to use, hopefully it will get known and get the popularity it deserves. The note features of it level up the browser, it works flawless and the developer is very active and responds fast to questions and requests in an amazing level. Thank you for this great addon!

This is really amazing! Settings for the notification with a green button for every circumstance and if set to open with page the notes popup opens with the respective tab: If there is no domain or page not it opens with global, if there is no page but domain note it opens with domain and if there is a page not it opens with that tab.
And it is compatible with Firefox for Android, if you use a Firefox release that allows to install add-ons from a personal collection.
I am honestly impressed.

Шикарное расширение, но есть недоработки:
1. Иногда заметка на странице существует, а индикатор (иконка расширения) не показывает этого - красный цвет. А иногда показывает - зеленого цвета. И приходится всегда, даже когда красного цвета, нажимать на иконку и проверять есть ли заметка на этой странице. Очень не удобно. (Исправлено)
2. При вводе текста на странице и нажатии перевода строки (Enter) происходит перевод строки и моментальное возвращение курсора в исходное положение - как будто были последовательно нажаты две клавиши "Enter" и "Стрелка влево (<-)". Очень не удобно. (Исправлено)
3. Очень не хватает автоматической синхронизации заметок. Я знаю, что об этом уже писали ранее, но я не могу не упомянуть этого.
В остальном расширение очень хорошее. Использую его очень часто.

UPD: всего за сутки разработчиков были исправлены 1 и 2 недоработки. Благодарю!
