Looks like a good waste of resources to implement things people don't want in a browser anyway, in a desperate attempt to get people to consider using Firefox again.

If I was Mozilla I'd allocate programming time to catch up with Chrome now that they don't have the phone OS thing anymore, instead of creating more distractions.

They really blew it. I remember a few years ago when I used both Firefox and Thunderbird as my default browser/email client...
