If you want to write your own password or a message, you may be annoyed if someone looks at your computer screen, but in this post you will be prompted to add a Chrome browser that will solve this problem. You just watch your computer screen.
Add-on called DECODELIA, the way this works depends on the addition of red filters covering the entire screen. In order to see what is shown on the screen you will need to wear red glasses, where you can only buy glasses and red color. When you wear them, you will be able to see what appears on the screen clearly.
So anyone can not see what you do on your computer, and if you want to restore the browser to normal, you will have to remove the add-on and restart the browser and will appear as it was.
