I can confirm this bug IS STILL PRESENT in latest firefox 3.1a1 - Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1a1) Gecko/2008072306 Shiretoko/3.1a1
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...

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