uBlock Origion Block WebRTC no longer works

Discussion in 'other software & services' started by ComputerSaysNo, Dec 16, 2016.

  1. Tested myself against ipleak.net and it showed my I.P address in the WebRTC field.

    It seems uBlock Origion Block WebRTC ption no longer works. This has not happened before.

    Anyone else have this happen?

    Running uBlock Origin. Just tested at ipleak.net. In uBO Dashboard, block WebRTC must be manually disabled; it is not disabled by default.

    Your IP addresses - WebRTC detection

    No leak, RTCPeerConnection not available.
     
  3. Use HenryPP's (latest chrome) chromium nosync (it is disabled in the source code).

    i use Adguard (for desktop) and no WebRTC leaking on IPleak.net.
     
  5. guest: I have a Adguard subscription but don't currently use it. Does it specifically block WebRTC in it's settings?

    In Edge, in about:flags - tick the "Hide my local IP address over WebRTC connections" option.

    Then no WebRTC leak.

    There is no issue. You just misunderstand the purpose of the setting. Read very carefully about it:

    > Prevent WebRTC from leaking local IP addresses

    Emphasis: "local IP addresses". I do warn about misunderstanding that part in the documentation[1], which is linked from the Settings pane. The purpose is not to hide your internet-facing IP address, which would be nonsensical (the feature is not named "Enable VPN"), it is to hide your local IP addresses.

    [1] "be cautious to not misinterpret the results of some WebRTC-local-IP-address-leakage tests found online"

    Thank you. Mistery solved. :D
     
  10. Yeah BUT something has changed though since the Dec 14th update. Before uBlock Origin did not show my IP address through WebRTC. Now it does.

    Please don't spread FUD, nothing changed with regard to that setting, and the test provided in the documentation shows this all works as intended, as it has always been. Two other posters in this thread weren't able to reproduce, and I wasn't able to reproduce any issue.

    If you really feel strongly about this, make the case with relevant technical details (steps-to-reproduce, what is observed, what is not observed but should have been, etc.) so that other people can reproduce (all old versions of uBO can be installed, so make the case that 1.10.2 is different than 1.9.16 with regard to that setting).

    Also, be sure you do not have another extension actually controlling the WebRTC setting in the browser, thus preventing uBO from controlling it -- this is why ALL details matter when making such serious claim, otherwise it's just FUD -- you don't even mention the most basic information such as which browser your are using.

    What IP address? Your internet-facing one?

  12. Just tried the check now and WebRTC is blocked. Sorry for the alarm.

    But WebRTC was leaking at one stage even with the option to block it ticked on uBlock Origion.

    Not sure why that happened. Maybe conflict with something in Chrome.
