Hmm, I tried the same and also had firefox-bin hang on startup -- and yet
running the system shipped build of firefox 1.5.0.4 worked fine. I
thought it may have been a path issue, but I haven't yet found the fix.

However, if you are on b53 then you may have firefox 2.0, which I just
ran with that version of HelperMonkey. So far it seems to be working fine.
I used the following while in the directory with libmozjs.so:

   $ export LD_PRELOAD=/usr/lib/firefox/libmozz.so:./libmozjs.so
   $ export LD_LIBRARY_PATH=/usr/lib/mps:/usr/lib/firefox  
   $ export MOZ_PLUGIN_PATH=/usr/lib/firefox/plugins
   $ /usr/lib/firefox/firefox-bin -UILocale C -contentLocale c

Hopefully that will be happier.

I suspect firefox 1.5.0.4 was hanging while trying to do the auto update,
so another workaround may be to skip that (somehow)...

cheers,

Brendan
