Using that method I can see that the libraries are indeed loaded.

Load a page with a plugin then run htop, you may see a few plugin-container child processes for firefox, note it's pid and then run (as root): cat /proc//maps | grep libxul.so You'll see something like this: 7ff264f9b000-7ff269e4b000 r-xp 08:06 8736977 /usr/lib64/firefox/libxul.so 7ff269e4b000-7ff26a04a000 ---p 04eb 08:06 8736977 /usr/lib64/firefox/libxul.so 7ff26a04a000-7ff26a4ef000 r--p 04eaf000 08:06 8736977 /usr/lib64/firefox/libxul.so 7ff26a4ef000-7ff26a56e000 rw-p 05354000 08:06 8736977 /usr/lib64/firefox/libxul.so f > How would it know to load libraries for other binaries? When firefox starts the plugin-container process it may just set the LD_LIBRARY_PATH environment variable for it, just like the script from the binary packages do, or it may do something more complicated.

Exactly, all the confusion over whether the firefox executable is a script or not come down to this, as does the location of libraries as they are bundled with the -bin package. -- Neil Bothwick Capt'n!

Anyways, what this means is that the library is not loaded by the loader but by firefox at runtime so it's nothing to worry about. I guess some versions or build use a script to preload the library.

Just have a look and don't pretend it's a binary file ;) $ cat /usr/bin/firefox-bin #!/bin/sh unset LD_PRELOAD LD_LIBRARY_PATH="/opt/firefox/" GTK_PATH=/usr/lib/gtk-2.0/ exec /opt/firefox/firefox "$@"
