This was first reported by users at mZ as a problem that had cropped up very recently: http://forums.mozillazine.org/viewtopic.php?p=3365817#3365817 http://forums.mozillazine.org/viewtopic.php?p=3366168#3366168 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.
TE seems to have been successful. They are reportedly working on a fix.
seems to be fixed now.
Confirmed as fixed starting evening of May 20th.
Well it's happenings to me, few minutes and failure to connect to Facebook chat, I'll then just refresh the page and its a quick fix for another few minutes...
