I am using brave on Windows 10 as well as on Android 7 & 5.1.1, and I really like it for the speed and the way ads are handled. However, since I am also constantly using VPN on all devices and checking that no private information is leaked, I noticed that BRAVE is leaking my (real) IPv6 Address when VPN is active. I am using the following version of BRAVE under Windows10 (current):
Update Channel dev
I ran various WebRTC Leak tests (e.g. https://diafygi.github.io/webrtc-ips or https://browserleaks.com/webrtc#webrtc-device-id or “ipleak”) and all are showing my real IPv6 and local IP addresses when using BRAVE, while no information is leaked when I am using Firefox. BRAVE is also disclosing much more device ID information than Firefox, but that should be a separate topic.
This means that BRAVE is leaking real IPv6 addresses when running under a VPN, which is a serious security / privacy issue. Although some posts mentioned that this problem might be solved, it is obviously not in my case / experience (e.g. the post / solution mentioning “about:config” settings does not work, as there is no “about:config” in BRAVE.).
Is there any way to switch off WebRTC like in other browsers? I found no setting so far that could solve my problem.
Thanks for any kind of helpful information. I will use BRAVE under Windows only with caution, but as long as this problem remains unsolved, Firefox remains my preferred browser.
P.S.: Interestingly the WebRTC check sites above show no IP Leaking for the Android versions of BRAVE, so this problem seems to be limited to the Windows version of the Browser.
