Chrome has entry to equally pages and also you may inform it to inject and run the payload.js script within the present webpage. Once injected the payload.js script can entry and alter the content material of the presently lively tab and ship messages again to the popup.js script employing the chrome runtime messaging service. Since we have set popup.js as a persistent background script within the extension manifest it'll retain listening for messages from popup.js till Chrome closes. But it perpetually will get the popup.html because the lively window not the chrome browser tab consumer clicked the extension icon from. You can get all tabs and inject code into them employing the chrome tabs API. To study extra about browser extensions, let's examine Google Chrome.

A Chrome extension is a system made from various modules , the place every module promises distinct interplay sorts with the browser and user.
