Extensions are published and are available on Google Chrome’s Web Store. Some of the websites that you visit or software that you install asks you to install their extensions as well.

The google chrome’s extension has become the preferred by Private Internet Access (PIA) HTTPS proxy and VPN service. The regions which come under Private Internet Access uses the proxy service TLSv1.2 to encrypt all the communication that happens between your browser and PIA.

The extension does not affect other application other than the web browser in which it is installed. It can also be used without or with the PIA desktop app. It supports making HTTPS, HTTP, and secure web socket entreaties through the proxy servers. Plaintext web sockets are not supported by PIA.
