cloud 9 not showing up

Hi I am new to BBB and when starting cloud 9 , it is getting stuck
I tried in waterfox & chrome,no luck!

Search the forums for a fix. I’d just tell you how, if I could remember, but I don’t . . .

Anyway this is a known issue, and it seems to effect Chrome most of all. As I recall, Firefox is not affected by this problem. But I think it is related to cloud9 sources being redone . . . something about closed source before, and now open source.

I tried in firefox, it came now !!
so looks like there is some issue with Waterfox & chrome.
