    Hey, sorry to hear that you're having trouble. Just to clarify—this extension has been fully tested and works on all major article websites. The method you mentioned (right-click → Inspect → Toggle Device Toolbar) is definitely known and useful, but it’s a basic, older approach and only supports limited, generic devices. In contrast, my extension supports testing across 85+ modern devices, including the latest phones and tablets. It’s designed for those who want a fast, accurate, and efficient way to preview websites on multiple devices without the hassle of manual setup. Feel free to try it again, and let me know if you face any specific issues—I’m here to help!

    I’m a freelancer, and this extension has made my life so much easier. I no longer have to worry about how a design will look on different devices—it’s all there with a click. The simplicity of installation and usage is amazing.
