Firefox plugin for Linux was tested on Fedora 10, by copying the files
npambulant.so and npambulant.xpt in ~/.mozilla/plugins
In the .zip file there a file README-linux is available, saying:
------------
Installation instructions for installing the AmbulantPlayer Firefox plugin
version 2.0.2 (xpcom version, works only with Firefox) on Linux (32/64 bit):
Move or copy the following files from this .zip file to:
$HOME/.mozilla/plugins
(or as root for system-wide installation to: /usr/lib/mozilla/plugins)

npambulant.so
npambulant.xpt

Restart Firefox.

For uninstall, remove above files.

Notes:
1. This is an experimental version. Sometimes when npambulant is loaded,
   Firefox may hang or crash.
2. The current version of npambulant is incompatible with nspluginwrapper.
   For root installations, you can disable nspluginwrapper by adding
   ":npambulant*" to the variable IGNORE_WRAP in 
"/etc/sysconfig/nspluginwrapper"
3. For a 64-bit version, copy npambulant.so-64 in place of npambulant.so 
in oneof the
   directories mentioned above.
4. This version was build with the following options:
   ./configure --prefix=$HOME CFLAGS=-fPIC CXXFLAGS=-fPIC --with-live 
--without-python --without-xerces --without-plugins --without-qt 
--with-npambulant LDFLAGS=-L$HOME/lib EXTRA_LIBS=-lfaad
-----------
Thus, there are  3 possible causes for your problem:
1. You're not using Firefox
2. You are doing a root installation without disabling nspluginwrapper
3. New, unknown problem that was never observed before.

As the plugin is being rewritten to use a newer interface (nruntime) s.t.
on Windows XP the plugin also works with Safari and Opera,  it may be
approptiate to test that version (must be build from trunk,  currently not
released yet).

Kees Blom.
