By default it only installs -security updates. But it is configurable
see /etc/apt/apt.conf.d/50unattended-upgrades.

Please use polite language =)

Generally you would want -security fixes as soon as possible.

Program is still in memory and their dynamically loadable libraries as
well. So it is quite stable. Icons & pictorial data can become
inconsistent but I haven't seen unattended upgrade to crash firefox

Also if you have low disk space things can get really interesting. I
once had less than 100MiB left on my harddrive and Firefox & Gtk look
really funky =))))) So is your free disk space fine?

I think I explained it in detail =) security only & you get a popup
that firefox needs restarting after you as a user decide when to do
it. Because user data in the browser is important.
