## Description

**User-Agent Switcher** is a versatile Chrome extension that allows users to quickly and easily switch between 26 popular user-agent strings. It features a convenient toolbar popup UI divided into four rows: mobile user-agents, desktop user-agents, desktop operating systems, and control options. Users can toggle user-agents after reloading the page, edit or copy the current user-agent, and specify particular URLs or domains for applying custom user-agents.

The extension also provides a status bar within the popup for real-time information and supports modifying default user-agents directly from the toolbar panel. For users needing custom user-agent strings, the developer offers another complementary addon. This extension is ideal for developers, testers, and privacy-conscious users who need to simulate different browsing environments with ease.
