It doesn't. libdbus-glib-1-2 is a perfectly valid package:

$ apt show libdbus-glib-1-2

The package libdbus-glib is dependency of firefox-esr, according to apt-get.

When I type apt-get install libdbus-glib, I get this:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package libdbus-glib

Ah, so there is no such package. Acknowledged.

Curious, I typed apt-get firefox-esr, and got this:

So how does firefox successfully pull in a dependency that does not exist?

Thank you.
