I recently upgraded Firefox to version 34, expecting to see the new Hello WebRTC feature that I read about on OMG! Ubuntu as well as Firefox Hello - video and voice conversations online and Firefox Hello: voice and video calls without account requirement .

However, when going into customization mode, I do not see the speech bubble icon. What am I missing? Is it not included in the release?


Well, it turns out that Mozilla his disabled this for most users. You need to go to about:config and set loop.throttled to false.

More info here: http://techdows.com/2014/12/fix-no-hello-button-in-firefox-34.html

From the above article:

Reason: Mozilla has intentionally not enabled the button for users, they’re not confident of their servers taking the load when users use this feature, that’s why they’ve set the throttling to 10%.


In more recent versions of Firefox, WebRTC is enabled by default. However WebRTC cannot be found in the user interface of Firefox directly, because WebRTC is basically a feature which is built in into many browsers.

However Mozilla has built its own system and user interface around it so you can use it in Firefox with a few clicks. Just click on the button with a smiley included in a speech bubble:

Besides this, Mozilla's website currently has a summary of the features of WebRTC and a big button you can click on to start a conversation, located: https://www.mozilla.org/firefox/hello/

Here is the support article link: https://support.mozilla.org/en-US/kb/firefox-hello-video-and-voice-conversations-online
