This extension is not updated.
Updated version: https://addons.mozilla.org/en-US/firefox/addon/ourstickys-sticky-notes/
Remember to save sticky notes before installing the updated version!

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

这个插件挺好的.
发现一个bug: 这个插件会导致 百度云盘中,和好友的分享对话框消失.测试过就是因为这个插件导致的.

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

Hey Fabrizio, pls update your wonderful stuff.
We can no longer scroll with new FF :-(

BTW
seems he do no longer support the extension, also the Homepage is no more working.
Very sad.

Hey Fabrizio, this is a truly great and valuable extension. But with recent FF updates, your app's broken. I can't scroll through a Sticky or easily modify the text. Can you have a look? Thanks!

A very good addon (maybe the best, with many options to config), but from yesterday it´s impossible, one created, to navigate the notes with arrow keys, or select with mouse the text inside. I´m not sure if the problem is only mine, or started from Firefox version 69.

Great idea! However, login for syncing with other browsers let me login when I first set up the add-on but no longer. Now I have to click on OurStickys icon, then on "download" icon in specific sticky for specific URL. For the moment, the note still appears when I go back to that URL. Will see if that continues.

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 had to disable this extension because it prevents RideWithGPS.com (a route planning web site for cyclists) from saving routes. Once this is fixed (if ever), I will re-enable it.

Sadly, this plugin prevents htts://supportsystem.com (a website that provides a customer support ticket system) from working properly. Specifically, when you try to close a ticket, you don't get the next prompt to give a reason, the screen just goes dark. I enabled/disabled about 20 plugins in my Firefox one at a time before I discovered this.

Very useful addition, highly personalized, but the synchronization does not work - I will try to synchronize the "json" file with third-party software. I hope to see working native synchronization. Thanks!
