20240702: Export/Import still doesn't work for now. So, there's no way of making backup for notes locally or online. Must be done manually.

20240627: Still the best Sticky Note for Firefox. Wish there's a way to choose where to store sticky notes contents, either locally or online.

20240620: I've removed this add-on before. The original author have passed away. Used the one "yoasif" released.
Stumbled on this add-on again, and it says "Last updated 2 months ago (26 Apr 2024)". I'll give this add-on another try.

I liked these features most:
1) the ability to stick a note while page is being scrolled
2) can change default settings for notes
3) notes are persisted and can be viewed in a single place

Kindly ask the developer to add the option of grouping notes by tag, domain and date.

very yay. I wish they were more easily portable between firefox profiles or using profile sync services (not necessarily untrustworthy mozilla services)

my quick fix:
add this Userstyle for all websites, to restore the selectability of note contents:

.__myNoteMainWrapper * {
user-select:text !important;
}
(for example with the stylus addon; you could change it directly in the notes.css of the addon, but I don't know how, it would be great someone would takte this addon in capable hands).

There is no better addon for this task, tried them all.

Best sticky note for every web browser.

I uploaded a fixed version here: https://addons.mozilla.org/firefox/addon/ourstickys-sticky-notes/

Unfortunately, the add-on developer has passed away: https://www.legacy.com/obituaries/name/fabrizio-parrella-obituary?pid=188112546

機能が多く使いやすい。
ユーザー間、またはブラウザ間の共有機能を付けて欲しいです。
フォントが小さいくて少し見づらい。

能增加字体颜色就好了,还有增加一个 便签的透明度.add fond color,
search by tag 不能模糊搜索!

If you used INTERNOTE in the past, this is very similar. Customizeable colored notes of any sizes and quantity attached to any position of the page of any URL, which appear consistently on each visit. You can also import and export all of your notes. Exactly what I was looking for. Thank you so much!

Love the idea, please keep working on it, to make it one of the big addons :)

I like this extension because it allows leaving sticky notes on websites you visit to review them upon return and each note also serves as a form of bookmark which will take you to that same site you left the note on. What I cannot seem to do with it is log in to sync between browsers in Firefox Quantum and I hope this is fixed or someone can tell me why so I can fix the issue. I'm still rating it 5 stars just because I think it's a great add on anyhow and reminds me of the controversy of having used uTok (Users Tree of Knowledge) app years ago which angered website owners because it allowed people to leave notes of any nature for other uTok users to view and those notes used their site bandwidth to view. This doesn't do any of that, but I still wish it had that feature! Not because I think it's alright to use someone's site bandwidth up, but because it's a great way to share sites people visit and like with the reasons they do (or dislike whichever might be the case)

It looks perfect, I'm impressed.

Excellent! I once used QuickNote for simple notes, but it became legacy after new FF. OurStickys is good enough for me. The notes are movable and are showed on each page.

I have used this Add-on for organizing and filtering literature in several tabs while writing a thesis.
It was a great help and worked exactly the way I wished such an Add-on would do :).
I didn't use or require the sync future so I can't tell anything about that specific functionality.
