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")

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.

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.

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?

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

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
