To install:

  % make
  % make install

The "make" step is optional and only compiles the modules, translations, and the
mmkeys extension.

Environment variables that affect "make install":

  FIREFOX
    Where Mozilla is installed. Default: /usr/lib/firefox
  LIBDIR
    The lib directory to be appended to PREFIX. Default: /lib
  PREFIX
    The installation prefix. Default: /usr/local

For example, if Mozilla is installed in /usr/lib/xulrunner, you can run
"make install" as:

  % FIREFOX=/usr/lib/xulrunner make install
