Frequently Asked Questions

How do I get it?

The WonderSwitcher is available from the Chrome Store, the Firefox Store, and the Microsoft Store for easy installation.

Why does it want so many permissions?

Browsers (correctly) consider setting a proxy to be a very privileged action, since you're voluntarily sending all your browsing information to another computer! In this case it's required since we are - by design - setting your proxy information.

How do I import proxies?

Click on the Import to Extension link on your WonderProxy servers page to automatically import your server list to the add-on. For information on how to manually add servers, view our user guide.

How do I set my password?

Click on the WonderSwitcher icon in your browser. Select Settings, then Credentials and enter your username & password. If you're a WonderProxy user, we'll verify your credentials.

Why is it blinking red?

You've set a reminder. This is helpful if you're prone to setting a proxy and forgetting about it.

How much does it cost?

The extensions are available for free.

Will the Switcher protect my identity?

The Switcher was designed to assist with testing, not identity protection. Websites may override the switcher's BrowserLocation hook to determine your actual location (if permitted). Additionally some browsers allow requests using ftp:// which are not routed through the proxy server, and would reveal your true IP address.
