"Create a sticky (…) Ctrl + Shift + C" is the combination used in Mozilla Firefox for Developer Tools.

Text in predefined fixed colors is hard to read in most cases:

There is no way to use the extension to set a color flag for web pages via the extension button indicator color. That is, it is enough for me to see that I previously set the current page to "red color" or "green color", without adding any elements to the page itself.

しばらく使っていると表示すら出来なくなってしまっている。何のタイミングなのか知らないけどそれまでのメモが一気に失われる。せめて自動でバックアップが取れるならば許容出来る。

needed this so badly

it's fine

Shocking extension - weird design

Does not retain notes on pages.

Worked well initially but I think the author periodically wipes out stored notes on his server. Not good if so. I've moved over to OurStickys which allows sync with Google accounts.

One of the few available Sticky Notes that is relevant (will tie to the specific website).
Doesn't have any option to tie it to the domain instead and also it eats up the side-bar, would be better to have a new tab/window for list instad (for those of us that use TST).

The only add-on currently available for this function.

would it be possible to revise to not require access to all my data for all websites? Not clear on why that would be. Thanks for your time

I really wish I could have rated this higher, as it is exactly what I needed except that it wasn't reliable. You cold not rely on a stickie sticking to a web page. You could return to that very page five seconds after having placed a stickie on it and it would not be there. Even if you hit hide/show stickies repeatedly. I relied on these stickies for short notes such as shipping costs or price per item reminders on products I was considering. It was disappointing that these stickies would not be there on the page when I returned.

In Sidebar dont have any option like edit/remove.

in sticky when we want remove note this app dont show alert to user. This bad because user can do miss click/wrong click.

does not work at all!
