Do you need a scriptable flash plugin or something?  All I get on Linux with Flash 7 is:

JavaScript error: , line 0: uncaught exception: [Exception... "Could not convert JavaScript argument"  nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)"  location: "JS frame :: https://bugzilla.mozilla.org/attachment.cgi?id=254463 :: boom :: line 9"  data: no]

Doesn't seem like a critical assertion. Boris, the reason you don't see this is probably that you're using Flash 7 which is scriptable through an XPCOM interface, not through the NPRuntime plugin scriptability API, so your embed.__proto__ is a different object.

I'm seeing this again (same testcase).

Now I get no assertion, but a slightly less reasonable error message than the error message in comment 1:

JavaScript error: , line 0: uncaught exception: [Exception... "Node cannot be inserted at the specified point in the hierarchy"  code: "3" nsresult: "0x80530003 (NS_ERROR_DOM_HIERARCHY_REQUEST_ERR)"  location: "https://bugzilla.mozilla.org/attachment.cgi?id=254463 Line: 9"]
