tba: Extension error: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMWindowUtils.removeSheetUsingURIString]"

Experienced another OOM and ANR in combination with this trace which slipped through so far: shows up repeatedly (5 times each) and happens daily according to my logs, also unrelated to ANR:
