Frequently Asked Questions

How do I get it?

The WonderSwitcher is available from both the Chrome Store, and the Firefox 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.
