This was first reported by users at mZ as a problem that had cropped up very recently:

Specifically, the chat application will disconnect after a short period of time (usually within a couple of minutes) with an error message indicating a connection failure.

I decided to take a look at the problem today, and found numerous errors like this in the error console:
Error: uncaught exception: [Exception... "Not enough arguments [nsIDOMWindowInternal.postMessage]"  nsresult: "0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)"  location: "JS frame :: http://www.facebook.com/home.php? :: anonymous :: line 7"  data: no]

Bug 430251 stood out as the most likely culprit, but just to be sure, I checked the tinderbox builds immediately before and after 430251's landing (20080502_1115 & 20080502_1313), and the problem was not present before but was present after.

I'm not entirely sure if this is a problem of Facebook needing to update their chat application for this new behavior (which they may be oblivious to, given how recently it landed) or if there is a bug in the implementation, but I'm going to go with the former for now, which is why I'm filing this in TE.
I have contacts at facebook, so if this is indeed a TE issue, I can point the right people at this bug. Waldo, thoughts?
It's TE.  There are real production sites seriously using functionality that's not in a single shipping browser and is just barely (barely) standardized?  Madness.
