What I've tried so far:
1.) Upgrading/updating flash to latest version.
2.) Disabled ALL Firefox extensions and add-ons.
3.) uninstalled and reinstalled ALL Firefox extensions and add-ons.
4.) Restarted browser and computer.
I've pretty much done everything besides uninstalling and re-installing Firefox which should be a last resort as I don't want to have to start backing up bookmarks/add-on/extension settings and also end my current session.
The funny thing is everything on Bloomberg.com works perfectly fine on the guest account of the same exact computer and my brother's.

That's how it should look.
What changed?
Firefox 3.6.x never gave me any such problems. :\
I upgraded to Firefox 4 on recommendation by the software only two days ago and I now almost regret it.
