I've installed the FlashEff2-extension as instructed but when I try to open the Flasheff2 panel, it keeps on loading (hangs). A screenshot of what I see in front of me right now:
Why isn't the panel loading and what can I do to fix it?
I figured out the problem: my firewall didn't allow Flash to make an internet connection (Flasheff2 requires an internet connection so you can log in to your Flasheff account). Simple as that :)
