MyStickies provides a very interesting yet practical service that allows users to create their own sticky notes while reading web pages, just like making notes on the corner of a page when reading books.
MyStickies makes full use of bookmarklets but adds very personalized features. It also offers a corresponding Firefox extension to help conveniently complete the task of sticking notes.
If you want to create a new sticky note, simply hold down the Alt key and click the mouse anywhere on the web, and a sticky note will pop up (let's call it a sticky note). Enter your notes and tags here, and holding down the Alt key while clicking above can change the color of the sticky note. Once created, the sticky note can be resized and moved arbitrarily, and tags can also be marked.
After completing these steps, you can log in to the original MyStickies site and see the sticky notes you've made, along with the recorded tags and related article sites, and the corresponding images can also be displayed.
