Mobile Device Simulator: Responsive Design Preview
The essential tool for web developers, designers, and QA testers to ensure perfect mobile responsiveness and user experience on any website.

The Mobile Device Simulator extension overlays a powerful, dynamic testing environment directly onto your current web page. Stop guessing how your site looks on a small screen—see it instantly, complete with a realistic device frame.

Key Features & Functionality
1. Realistic Device Frames: Preview your website wrapped in high-fidelity, CSS-modeled device bezels (inspired by popular iOS and Android devices) for an authentic testing experience.

2. Instant Viewport Switching: A dedicated, persistent sidebar provides a curated list of standard mobile viewports (e.g., iPhone 14 Pro, iPhone SE, Pixel 7, Galaxy S22). Click any device name to instantly resize the frame and see how your CSS media queries react.

3. One-Click Toggle: Easily activate and deactivate the simulator using the extension icon. The extension instantly takes over the current tab with the testing overlay and restores the normal view with a second click.

4. In-Place Testing: The tool loads the current page URL into an iframe, allowing you to interact with the site, click links, and test form submissions while viewing it in the device frame.

5. Full-Screen Coverage: The simulator deploys as a fixed, full-screen overlay, ensuring no interference from the browser's native window or toolbars during your testing session.

6. Visual Consistency: Features a clean, professional, dark-mode sidebar and a light staging area, mimicking professional testing environments like Flutter's Device Preview, to keep focus on your application.

Why Use This Extension?
1. High-Fidelity QA: Catch layout shifts, hidden scrollbars, font scaling issues, and navigation problems specific to small screens before deploying.

2. Saves Time: Eliminate the need to constantly resize your browser window or use built-in, less visual developer tools.

3. User-Centric Design: View your application exactly as your users will see it on their phones, helping you build truly responsive and accessible interfaces.
