Microsoft Internet Explorer 11 - the last in the series - was released in 2013. Edge is now Microsoft's main browser.
Although Microsoft say they will support IE11 until 2025 but 'The Internet' disagrees. Yahoo and now Twitter (along with many of main development websites) are no longer supporting it. It will soon be dropped by the others.
This will inevitably impact Users' experience of technology platforms including Passle.
