On March 2, 2021, Microsoft released Power Automate Desktop for Windows 10, an official Robotic Process Automation (RPA) tool. This tool will come standard with Windows 10, but since it was already available for download, We can use it now.
After installing it, will pop-up a dialog box with 3 types of browser extensions for this Power Automation.
So I tried the firefox one.
After login with your MS email. You can not start to use it.
