The libmozjs library undergoes fairly disruptive changes.
Back in 2011 some interfacess in a new upstream release of libmozjs
changed and after some failed debugging I disabled it. From my experience the
support was very limited anyway. I cannot remember a website I use that was
usable with elinks's Javascript some. Sometimes even the contrary; if no
Javascript is available websites fall back to a non-JS version, while with
Javascript the websites fails due to the limited scope of JS support in elinks.

If elinks from unstable works again with current libmozjs from unstable.
please file a bug against elinks and I'll re-enable JS support in the
next upload.
