The atom error starts again

Today when I opened up my Firefox window the first thing that I saw was the error above. What is the problem with blogger lately, their atom especially? Is it an extension problem (most likely not the extension) or a blogger problem, I'm not sure about that (because I can still seem to blog with ecto, and the review on ecto will be posted soon) but we'll see about that. You can never know what the error is until you dig deeper.

firefox, blogger, performancing, atom, error
