Receiving msg, failed to set up flash, JSON: Stringify can not serialize cyclic structures

[Boots178]

When visiting a webisite I have previously had no problems with, I am now seeing a msg appear Failed to set up flash, and a second msg, JSON: Stringify cannot serialize cyclic structures. I have tried clearing my cache on safari, resetting my history and re-installing flash. I am not sure what else to do

To give you any useful advice, I'm going to need to know more about your computer and browser:

It seems it happens only on Firefox. As much as I love the browser I'll use IE or Google. It's easier than playing around this. Mozilla just doesn't accept flash player any more.

If it's a public website, I'd be interested in looking at it to figure out what changed.
