The old applet was using gtk3 since 2012. There are issues with gtk2 and
introspection. The use of pygtk was also not an option because of
missing python3 support, it also pulled in gobject, which then
conflicted with dbus.

Yes, there have not been issues in Xfce for also all the time. But there
have been lots of issues with Gnome3. I had work arounds in the applet,
but those were not working with all Gnome3 versions.

See above.

I do not see this in Xfce. Do you have special panel settings?

There is also a Qt5 version, but it behaving strange in KDE5.

Shields-up/-down was settings the default zone in firewalld. There is no
runtime only setting for the default zone, therefore it was setting it
for the whole system in a persistent way.
If there is a request, I will add it to the new applet.

Oh yes, I forgot to adapt the man page. Thanks for finding this one.

As far as I know there is no command line tool for this. You can
create/change ~/.config/firewall-applet/firewalld.conf
The names here are bad, so I hanged them to
~/.config/firewall/applet.conf:
