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.

User reviews

The User-Agent Switcher add-on is appreciated for its simplicity and ease of use, especially by developers and users needing to spoof their user agent for specific tasks like downloads. However, the main criticism is that its built-in user agents are outdated and not updated, causing compatibility issues on modern websites like YouTube and Cloudflare. Additionally, the lack of a manual input option and occasional functionality issues on newer Firefox versions reduce its reliability for many users.

Pros

Simple and easy to use for switching user agents.
Allows selection of which sites it should act upon.
Excellent for web developers and certain use cases like accessing Windows ISO downloads.
Effectively performs the basic function of user-agent switching.

Cons

User-agent options are outdated and not updated regularly.
Lack of manual input for custom user agents.
Does not work properly on newer Firefox versions for some users.
Some users report it does not actually change the user agent as expected.
