Finally some change. It still doesn't work but it throws some error at least. I've test it in today Minefield (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2pre) Gecko/20081027 Minefield/3.1b2pre) and it shows these 2 messages in debug console:

Error: uncaught exception: [Exception... "Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsISupports.QueryInterface]"  nsresult: "0x80004002 (NS_NOINTERFACE)"  location: "native frame :: <unknown filename> :: <TOP_LEVEL> :: line 0"  data: no]

Firefox 3.1 beta 3 - Still doesn't work, but no more exception is displayed, so we are back in pre-3.1beta2 stage
