To use the Selenium IDE I need to:
        
        install several Web Browsers we have Edge, Chrome, Firefox
                
        Next I need a Selenium Plug-in to build my tests
        
        the Selenium Plug-in is available for Chrome or Firefox only
        
        I will use Chrome or Firefox to write my tests, but
        I can run my tests in "any" Browser including Edge
        (I have to do some setup to use Edge)
