Flash website is not loading in firefox, but loads in Chrome - how do I debug / fix this?

When I go to a flash web site that I have a subscription to (stock market data), it does not load, but the same page loads in Chrome (Chromium). That is the best info I have right now. I have latest flash on firefox 18.
Actually, this occurred to me later this afternoon, but I use Gentoo, which normally builds from source (cuz I am hardcore like that). I uninstalled the normal build and reinstalled the prebuilt binary and everything works. I am happy again and just need to play around with the source build options, which I can do later.
