He probably just assumed it did, like all other chat services.
Whether it does or doesn't, if it's not installed, then you don't need to worry about it. I'm quite annoyed that firefox is adding more cruft, more buttons, more features. Just like phones and operating systems, I now first go to the hidden places necessary to turn off apps/buttons/features that aren't needed and needlessly clutter and the interface, slow down the system, and cause unexpected issues. Then I add the extensions required to get the power-user settings/tweaks which actually should be there.
It is VERY FRUSTRATING that the trend is solidly in the direction of removing "scary" relevant settings and adding crap features, and in many areas, there is no longer a good option for people like me who know what the fuck they're doing. Modern "products" waste more and more of my time.
Mozilla has a Firefox Hello Terms of Service:
https://www.mozilla.org/en-US/about/legal/terms/firefox-hell...
which claims to link to the Firefox Hello privacy terms, but actually links to the main Mozilla privacy page:
https://www.mozilla.org/en-US/privacy/
which, in a sidebar, links to the Firefox Hello privacy policy:
https://www.mozilla.org/en-US/privacy/firefox-hello/
which links to the TokBox privacy policy:
https://tokbox.com/support/privacy-policy
which says:

So, yes, it snoops on your contact information.
