So I am asking for your help on how can i implement my idea, means what api or example code should use for overlays image object on screen. I see some popup implementation but it remain join with extension menu button.
The .crx file of a Chrome extension is similar to the .xpi file of a Firefox extension. If you “unzip” the file into a folder, you can inspect its contents.
Thank you very much Sir for you the suggestion.
shimeji .crx unzip files is a little complex .class code for me to de-compile and understand that I can rewrite individually and I started few days before.
