FF9 no longer connects to Lightstreamer

[webfg]

I have a similar problem with FF9: Lightstreamer doesn't work.

In my case, when try to execute pushpage.bind(), the page reloads itself but hangs and i get in the firefox console two errors:

LS_lhL is not defined

and

attempt to run compile-and-go script on a cleared scope

This page works fine with others browsers and FF8.
