Just discovered this today. Just what I've been looking for after the end of omnivore app site about a year ago.
However, it's missing a crucial feature: ability to add tags to your notes & ability to search via tags. Examples of tags: #science, #people, #coding. etc.
Please add something like that.

EDIT: After explanations from the author, works like a charm. Many thanks!

Surely a very useful extension and a great idea. However, I can't see the (green or whatever colour it is) notification either on the page where I left one, nor in the toolbar (there is no extension icon). Without it, it is unfortunately worthless, at least for me.

In addition, I can see the possibility of adding a note only with the keyboard shortcut; there is nothing in the right-click menu, and there is no tool on the toolbar. Perhaps something is wrong with my settings, but I can't figure out what. This leads us to one suggestion, if I may: there are so many things to configure, which is nice, but when users search for basic functionalities, too many other settings are a distraction.

Keep up with great work!

Edit:
1) Title is visible and editable - right.
2) Posting makes FF ask for a further permission,... but that's kinda unnecessary, since this 'posting' should occur anyway, so why isn't the permission added to all the others asked for while installing the AddOn...?

Apart from that - works!

Reminds me on an old FF Extension (a pre-web-extension-AddOn called "Sticky Notes")

Keeps refreshing... I can't write anything most of the time. And it happens after its been working for a while, and then suddenly the text cursor thingy goes to the very start making me unable to write anything at all.

Excellent extension! It would be perfect if it allowed notes to be saved locally.

Estensione essenziale e ben realizzata. Le note per sito, la modalità post-it e la sincronizzazione funzionano perfettamente. Il developer è attento e risponde velocemente. Indispensabile per chi lavora online. Complimenti, merita tutte le 5 stelle!

Uso Notefox dal giorno della sua pubblicazione, estensione a me molto utile.
Purtoppo recentemente si sono verificati molti crash di Firefox apparentemente dovuti a Notefox, in particolare su Windows 10. Ultimamente si è rilevato che i crash erano causati da Firefox ed il bug è stato corretto da Mozilla in Bugzilla dove lo stato risulta "risolto".

Complimenti allo sviluppatore ed a tutti quelli che hanno contribuito a risolvere questo problema 5 stelle è tutto meritato per questa estensione.

I have been using Notefox since the day it was released, and I find it very useful.

Unfortunately, there have been many Firefox crashes recently, apparently due to Notefox, particularly on Windows 10. It has recently been discovered that the crashes were caused by Firefox, and the bug has been fixed by Mozilla in Bugzilla, where the status is now “resolved.”

Congratulations to the developer and everyone who contributed to solving this problem. This extension deserves 5 stars.

C'est une super extension ! Elle permet de prendre des notes et de les afficher sur l'écran ("sticky"). J'adore le compte Notefox. Merci.

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.
