How To Test Firefox Hello, Mozilla’s New WebRTC Video Call Service

Wow! Mozilla’s new Firefox 34 includes a great new WebRTC-based feature called “Firefox Hello” that lets you call people without requiring them to have an account with Firefox. You simply send them a URL via email, chat or some other method – and they can start calling you from within Firefox.

Here’s all you need to do to try it yourself. First, you need Firefox 34, of course. Once you have upgraded or installed the software, you should see a “Hello” button over on the far right side of the browser’s top bar:

Firefox hello button

If you don’t see this button, as I didn’t, you may have to perform the following steps, as documented in a Firefox help page:

1. Open the “Customize” section of the browser to add the “Hello” button to your menu bar:

Firefox customize

2. Drag the “Hello” button to the browser bar or to the drop-down menu.

Now, in my case, that still didn’t work and I had to use the additional trick mentioned in the help article of going to http://about:config and changing “loop.throttled” to “false” (simply by clicking on that setting). After restarting Firefox I was then able to go into the Customize window and add the Hello button to the browser.

Initiating A Call

Once the Hello button was visible I just had to click on it to get a URL that I could pass along to someone:

Firefox hello url

I posted it, somewhat ironically, into a Skype chat where a number of us who are “early adopters” of VoIP tech hang out… and Dick Schiferli (of Pamela fame) soon clicked the link. The call request window appeared in the lower part of my Firefox window:

Firefox hello request

The first time we tried Dick was signed in to a Firefox account but I was not. We got an error and the call couldn’t connect:

Firefox hello call failure

Now, I don’t know if this was a transient error caused by so many people trying it out… or if this was an issue with the “guest” access, but a few minutes later when I was also signed in Dick and I had no problem connecting:

Firefox hello call in browser

And there we were talking!

Cross-Platform Testing

In a good test of cross-platform interop, Dick was using Firefox on Microsoft Windows 8 and I was using Firefox on Mac OS X. The quality both in terms of voice and audio was great. We did notice one interesting difference between the platforms. On OS X I had an arrow that let me “pop out” the Hello window into a separate window that I could then resize and move around my screen:

Firefox hello pop out

There was no way for either of us to simply click a button and make the conversation go “full screen”, but with this pop-out window I was able to resize it to take over most of my iMac’s screen.

Missing Chat…

Interestingly, one of the things I found missing from our experience was any form of integrated chat. I wanted to share with Dick a link to a screenshot of what I was seeing on my computer and wound up sharing that link through a Skype chat.

I don’t know that I need chat… but I found it curious that I would just expect chat to be available. Given that Skype and Google+ Hangouts both offer this, my expectation does make a bit of sense.

Further Testing…

Given that I just created my Firefox account today, I couldn’t test the use of contacts as documented in the Mozilla blog post about the beta of Firefox Hello. I look forward to doing so. I also want to go back and try it again when I am not signed in to verify that guest access does indeed work.

All in all I was quite impressed with the ease and quality of this first public release of Firefox Hello!

    With regards to text messaging — we’re still in early days with the Firefox Hello feature, and plan to add a lot more over the next several releases. Part of why we’re not going out with everything all at once, like a lot of services do, is that we’re committed to doing them in a way that is consistent with Mozilla’s core values [1]. For instant messaging, this means that we need to do things in a way that’s secure and private above and beyond most popular services. And we need to do this in a way that is satisfying and useful for our users.
    For example, if you look at the most popular services on <,”>https://www.eff.org/secure-messaging-scorecard>, you’ll see that there are some pretty important properties missing. You cite Skype and Hangouts; find their lines in that chart and look at how they rate. We have to do better than that before we can put the Firefox brand on a messaging service, because our users have certain expectations around how we value their privacy. Getting this right is tricky, and that takes time. We know that people find this valuable, and it will be part of Hello. But not until we can get it right.

    As far as I can tell, the encryption for Firefox hello is currently set to 128 bit with perfect forward secrecy. I hope the encryption gets better with 256 bit, perfect forward secrecy, and GCM ciphers.

    mozilla is good very good with this above features, and i have left recently google chrome to come back to Firefox again.
    BUT my small additional crucial requests
    1) make chat integrated feature
    2) make these audio/video talking + chatting as the feature for “firefox for android” too
