WebRTC in itself is important to understand is a browser feature, not a VPN feature. Still it's always highly recommended to test/check for any so called WebRTC leaks. Especially if one is using a VPN as one of the main feature of a VPN is after all to hide/block your Local machines IP. More then likely also a reason why most WebRTC leak tests are found on VPN vendors sites. It can not be repeated enough as people sadly starts use VPN services and still very unnecessarily gets their Local IP revealed.
Today many browser vendors include a built-in option that easy can disable WebRTC if wanted/needed.

Latest stable Edge Chromium version along with a VPN I don't know if it actually leaks ones local IP. I could confirm if I had it installed. @rockstarrocks and @South Park result says it don't. This is without any extra extension/add-on like AdGuard or uBO etc if I understood correct.

A few more WebRTC leak tests that I can recommend.

Some VPN protocols block the leak on their client. But, this isn’t about a vpn leak it’s about disabling the function of WebRTC not working in uBo I think.
I thought we were talking about "WebRTC Leak". I mean if you connecting to a website w/o a VPN then why would you care about WebRTC showing your actual IP address, it already has your actual IP address. Why does it matter if it's getting IP via WebRTC? Treat me like a noob, I just wanna understand this.
I have two VPNs and neither of them are leaking my IP (or should I say actual IP) via WebRTC.

It says there is a leak but that's not my IP, that's the IP of VPN server. So is it a leak????:unsure:

Nope. That is not a leak. For example if your ISPs IP or your routers IP is shown, that's a leak you should be concerned about. Extra so if your Local IP is there in the test. That's the worst scenario and a major Red flag/warning.

Your VPN providers IP is a perfect result and shows your VPN works. (y)

Oh you're not a noob. It's a popular discussion among people talking about VPNs. But, in this case this is happening for people using uBo with the setting to disable it (without a VPN). If your VPN is blocking/changing IP it then it isn't testing if uBo is working to disable it.

I hadn't disabled the WebRTC setting in uBlock Origin's Privacy section. I also do not use a vpn. So, is it an entry in an import? Or a firewall rule? Theoretically, it seems you can achieve a green, leak-free result without a vpn or even disabling that setting, but it's not always clear how this happens. Not looking a gift horse in the mouth, though.

Hiding public IP address of WebRTC only makes sense when you are using VPN to hide your IP address.

Edge has an option to open an application guard (hardware virtualized) sandboxed window and now Windows Defender has an option to run sandboxed, when would we see them combined (Edge Content Processes running in real hardware virtualized environment)?

I shut it off and this is the result Could it be a rule of H_C Firewall Hardening which I put back on here. Perhaps, if Andy Ful sees this portion of the thread, he can provide valuable insight. These browser leak tests use Javascript? Edge remains set to "Strict."

I don't have any other security at the moment b/c I'm evaluating this installation of Windows versus going to an Insider build.

Rock-steady here. chromium Edge plus BitDefender's blog page.


Runs fine here, even smoother then on your firefox gif
The gif is not smooth enough so it's looks a bit laggy there.
Disabling extensions don't fix it either so not sure what's wrong. Anyway, this is the only page with this issue so won't bother much.
