How to Fix XPCOMGlueLoad Error of Tor Browser Due to Missing File on Fedora 39 KDE Plasma Spin

If you install the Tor Browser's launcher via sudo dnf install torbrowser-launcher and then installed the browser via the launcher on a freshly installed Fedora 39 KDE Plasma Spin system, you may encounter this problem. In this scenario, the browser can not be launched and CLI says (with --verbose):

XPCOMGlueLoad error for file /home/$USER/.local/share/torbrowser/tbb/x86_64/tor-browser/Browser/ cannot open shared object file: No such file or directory
Couldn't load XPCOM.

The solution is easy as follows.

Installing Missing Dependency

Install a package named dbus-glib.
sudo dnf install dbus-glib

Retry to launch the browser now.
