WonderProxy is a brand that specializes in providing global proxies for interactive testing and localization. With their WonderSwitcher browser extension, you can easily switch between any of their 261 worldwide servers in Firefox, Chrome, or Edge. This enables you to start your testing sooner and complete it faster.

The key features of WonderSwitcher include the ability to perform interactive localization testing in your browser, test websites localized with geoIP or browser geolocation, import proxy servers directly from your WonderProxy account, and easily find and switch between proxies. You can also star your favorite proxies for quick access, set filters to include or exclude domains from proxied traffic, and add an arbitrary HTTP header. WonderSwitcher is available for free from the Chrome Store, the Firefox Store, and the Microsoft Store for easy installation.

By importing your WonderProxy servers, the extension authenticates with them using a proxy token, eliminating the need to enter your password. While the Switcher helps with testing, it does not provide identity protection, as websites can override its BrowserLocation hook to determine your actual location
