In the MeAggregator project I need an Xmpp chat connection from plugins to the central FFS (don't mind if you don't know what an FFS is…) And I have tried using several Javascript libraries (Xmpp4js, JSJaC and Strophe) from within XUL, all of which ended up in hilarious fun and no resulting xmpp connections to the openfire server I'm running.

I've now found that I probably should  have used the Firefox add-on search instead of google to find these libraries, as this morning I found Xmpp4moz which is a library dedicated for xmpp connections from within Mozilla extensions (also other than firefox extensions), so I now have a connection through to the openfire server and the real deveolpment can commence…
