About Mobile Mockup Previewer & Responsive Tester

Mobile Mockup Previewer is the ultimate visual QA and presentation tool for web developers, designers, and site owners. Instead of just resizing your browser window, this extension embeds your active tab into a beautiful, pixel-perfect smartphone device frame. This allows you to view your website exactly as a user would on their phone. 🌟 KEY FEATURES: 1. One-Click Mobile Preview: Instantly wrap your current webpage in a sleek smartphone mockup frame. 2. Visual QA & Bug Detection: Does your site have an annoying horizontal scrollbar on mobile? This extension acts as a strict sandbox. If elements are overflowing, you will instantly spot the layout bugs that ruin mobile experiences! 3. High-Res Mockup Export: Click the "Capture Mockup" button to instantly generate and download a premium, high-resolution poster of your mobile site inside the device frame. Perfect for client presentations, portfolios, or social media! 4. Bypass Frame Restrictions: Advanced under-the-hood engine ensures that even sites with strict X-Frame-Options can be perfectly previewed. 5. Smart Scaling UI: The mockup device automatically scales to fit your desktop screen perfectly—no double scrolling required. Stop guessing how your website looks on mobile. Catch layout bugs before your clients do, and export stunning presentations in one click!
