[RESOLVED] Problems with Newgrounds.com

[Dwedit]

I'm having problems getting Newgrounds.com working. I'm using Firefox Nightly.

The site shows flash files fine with the extension completely disabled.
But otherwise, the site will end up with the Flash object invisible. You can still hear it play audio. It still appears on the "list of blockable elements" in Adblock Plus, but I can't see it anywhere on the page.
Sometimes, when I had "allow scripts globally" turned on, it will successfully show the flash, but it goes away when reloading or using the back/forward button. I also managed to occasionally get it to appear without the "allow scripts globally" setting turned on, just allowing several of the domains.

Edit:
Strange! I just updated Nightly, restarted, and Newgrounds seems to be working fine now. I wonder whether it was Mozilla or Newgrounds who fixed their code in the mean time?
