Is Mobile View: Test responsive designs fast safe?

Low risk

Mobile View injects a responsive-design overlay into web pages and stores device-selection preferences locally via chrome.storage.sync.

The extension adds a panel to any visited page that renders the page at multiple device screen sizes simultaneously. Device selections are saved to synced browser storage and restored on subsequent visits. All processing occurs locally; no browsing data or page content is transmitted to external servers.
