If you are using a browser that is supported by the KProxy Extension, it will automatically use it as your proxy. 

With the support of the extension, you can browse all web sites in your browser, like Chrome, Firefox, etc. through a web-based proxy. You can also surf them as if you were in the LAN (Local Area Network) environment because KProxy Extension works with some types of Internet proxies that are installed at your work or university, like Apache, Squid, Nginx, etc.

Besides that, it is possible to choose a virtual server of a domain that you want to proxy to surf the web. You can also use it to browse the Internet.

Finally, you can set the KProxy Extension to work as an HTTP proxy.
