This is no longer a top ten error and according to https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Dead_object comes from Firefox addons. For this reason I'm filtering out the error and declining this bug.

"he JavaScript exception "can't access dead object" occurs when Firefox disallows add-ons to keep strong references to DOM objects after their parent document has been destroyed to improve in memory usage and to prevent memory leaks."

Note: Only 29 instances in the last 24hrs.
