Mobile FIRST includes Sonoff NSPanel Pro: your page displays in a viewport of 480 x 480 pixels, with the model's User-Agent, touch events, and scrolling behavior of a real mobile.

This is where the difference with Chrome DevTools' responsive mode is seen: DevTools resizes a window, the extension replicates the device's browser and allows exporting shareable screenshots and videos.

1. 01 Install the extension — Add Mobile FIRST to Chrome, Firefox, or Edge. Installation is free and requires no account.
2. 02 Open the page to test — Go to the URL to check, including a local address like localhost:3000.
3. 03 Choose Sonoff NSPanel Pro — Select Sonoff NSPanel Pro from the list of devices. The viewport switches to 480 x 480 pixels, and the mobile User-Agent is applied.
4. 04 Check rendering — Scroll, change orientation, test your forms, then capture an image or video to share.
