## Description

Mobile View Switcher is a lightweight Chrome extension that enables users to toggle any website to its mobile version with a single click. By default, it mimics an iPhone running iOS 13, but users can customize the mobile user-agent string to emulate other devices through the options page. Simply install the extension and use the toolbar button to switch the mobile view on or off—the icon turns yellow when active and grey when inactive.

This extension is perfect for web developers and everyday users who need to quickly preview how websites appear on mobile devices. Custom user-agent strings can be copied from various online sources and pasted into the options page to tailor the mobile emulation to your preferred device. For bugs or support, users can report issues via the addon's homepage. An informative YouTube review is also available for a visual walkthrough.
