The gnash Plugins send javascript: commands when urlOpenerFormat is set.
This Shellscript can fix this problem.
[CODE]
#!/bin/sh

###
# Use the following command format to open urls if
# no host-request FD was given.
#
# The '%u' label will be substituted with the url
# to open.
#
# NOTE that the NPAPI plugin provides an host request FD
# to send url opening requests to.
#
# Default: firefox -remote 'openurl(%u)'
#
# set urlOpenerFormat browser.sh '%u'
