Where can I disable WebRTC and PeerConnection?

I had read that in FF v22 Web RTC (Real Time Connections, PeerConnection and DataChannels) are enabled by default. This is a big no-no for me.

Where can I turn them off, is it possible to do this in one click (as for JavaScript or images)?

Will they bypass disabled in Windows Remote Access service?

Anything else I can do to block peer-to-peer and any remote access to my computer, while reading the Web will remain possible?

Thank you.

Set media.peerconnection.enabled to false in about:config.

hello, of course there's no automatic peer-to-peer access to your computer while you're surfing the web. in case a website is making use of those capabilities to offer their service, you will presented with a panel which asks if access should be allowed (similar to how the access to geolocation is handled today).

Try this demo page http://mozilla.github.io/webrtc-landing/gum_test.html

Although enabled it will still warn you before sharing. I will try to work out how to disable it,I imagine there will be a pref.

I did find two prefs that I thought were related to disabling WebRTC but they do not seem to work for me even after a restart.

  • media.navigator.enabled
  • media.navigator.permission.disabled

You could try them and see if they work for you

  1. go to about:config
    see http://kb.mozillazine.org/About:config
  2. accept any warning
  3. use the search (my take a few seconds) filter for media.navigator
  4. right clicking gives you options to reset or toggle values.
    In most cases the effect is immediate.

Thanks Gingerbread_Man
but I have tried that myself just now and it is not preventing me using WebRTC video, although the value is remaining as false in about.config before and after I try.

  • media.peerconnection.enabled;false

Have you tried it yourself does it work for you ?

Be careful with media.navigator.permission.disabled:

// Developer preference for turning off permission check.
if (Preferences::GetBool("media.navigator.permission.disabled", false)) {
aPrivileged = true;
}
// Make enabling peerconnection enable getUserMedia() as well
if (!(Preferences::GetBool("media.navigator.enabled", false) ||
      Preferences::GetBool("media.peerconnection.enabled", false))) {
  return NS_OK;
}

Hi Cor-el,

I do not understand c++ but I see

Presumably it should not ordinarily be used.

  • media.navigator.permission.disabled

has a default value of False.

What is the correct answer to the op question please. Is it not possible to totally disable this feature now ?

As I mentioned above Setting media.peerconnection.enabled;false is not disabling the feature for me.

Thank you all! It was very helpful.

"you will presented with a panel which asks if access should be allowed"

This site seems to be able to use it without any permission popup: http://www.sharefest.me/

on the page you have to actively drag content into the page for an action to be triggered - i don't think this is anything new in particular, since drag & drop file uploading (in gmail, google image search, dropbox, etc.) is working for quite a while before firefox 22 was released already...
