> If you intend to test for leaks using other third-party sites, I recommend using Tor browser, because it's been hardened to block WebGL fingerprinting, and otherwise to report the same fingerprints for all users. But you obviously don't want to use Tor while testing your VPN. First, download Tor browser for your OS. Do that with your VPN connected, so your ISP doesn't see. After extracting, start Tor browser. You can probably accept all defaults. Go to advanced network settings, and select "No proxy". Browse about:config, and toggle both "extensions.torlauncher.starttor" and "network.proxy.socksremote_dns" to "false". Then browse check.torproject.org. You should see "Sorry. You are not using Tor." and your VPN exit IP address.
