I'm unable to even post a discussion topic in the forums when using Firefox.  Attached is a .png showing a side-by-side comparison of IE vs. Firefox when trying to make a post to the SW forums.

Left side is IE, where the text editor shows.  Right side is Firefox, where it waits and waits for the text editor applet to appear.   Is this a known issue?   Are there plugins missing from my Firefox install which might help this along?
