Java error??

[tinpanalley]

Can someone tell me what this Java error means? It's driving me bonkers...

Components.classes[cid] == undefined

Is this actually java, or javascript? Googling points towards the latter, and seems to usually relate to firefox plugins.

Removed one of my plugins and seemed to fix the prblem.
