Securing Firefox's position

I read this article about Firefox’s fights for relevance.

Could an integration of the SAFE Network protocol help it?

I tried “Hello” from my computer upstairs to my mobile (moms downstairs) and it was loud&clear. A better working mobile version of “Hello” would be super (and make my dream come true to make free call through mobile without to much fuss).

Btw the set up was:
I fired up Firefox on my computer to start "Hello"
Then copied the link to my mobile in Chrome and voila it works!

What is also great you don’t need a username or password. To bad that you don’t have a QRcode that you can scan, but you can import the link to https://qrcode.kaywa.com/ and generate one.
