Hi Scott,

Nope, we have not seen this warning in the console window of Firefox before. The warning shouldn't cause problems however and can safely be ignored. At this time, We are unsure of what could be creating an unbalance tree.

Hey Scott,

I think a few of us have seen these. However, most development and support is focused for Chrome which supports our largest set of features and can handle areas like this better.

As noted in the mozilla url, we are probably writing some output to the dom using document.write() and as such mozilla performance suffers. If you are doing any type of work where the browser performance is a significant hurdle, it is suggested that you use Chrome.

If this particular issue warrants further investigation please let us know and I will open an issue to myself on this.

Thanks,

-Aaron
