  I've got Seamonkey 2.31.  Go to 
Edit ==> Preferences ==> Category;Browser ==> Helper Aplications

  Assuming you've already got "Content Type" "PDF file" in the list,
click on the icon beside "emacsclient" in the "Action" column.  This
opens a dropdown menu.  Click on "Use other..." and navigate to
/usr/bin/mupdf in the file menu.

  If you're really brave, you can try editing the mimeTypes.rdf file in
the browser profile directly.  Remember to shut down your browser, and
back up the file first.

  I originally got into this because of a particularly obnoxious
behaviour by Firefox.  Seamonkey shares most Firefox code, so I assume
it follows suit.  The obnoxious behaviour is that it dereferences
symlinks.  Years ago Abiword would actually install a binary like
/usr/bin/abiword-1.2.3.4 and /usr/bin/abiword was a symlink to this
file.  Let's say you selected abiword as the helper application to
launch when you get Word files as URLs.  Firefox would dereference the
symlink to /usr/bin/abiword-1.2.3.4, and store that app name as the app
to launch for Word files.  A version bump to /usr/bin/abiword-1.2.3.5
and Firefox would whine about /usr/bin/abiword-1.2.3.4 not being found.
I edited mimeTypes.rdf, changing all "abiword-1.2.3.4" to "abiword", and
things worked properly.

  This was even more crucial for apps like "sox" which have symlinks
with different names like "play" that take different parameters and act
differently depending on the name you invoke them by.
