XF 1.1 Error Console: TypeError: can't access dead object

[Veer]

On a XenForo thread page, I'm seeing this by pressing Ctrl+Shift+J Error Console

Error: TypeError: can't access dead object
Source File: chrome://swfcatcher/content/swfcatcherOverlay.js
Line: 291



Do you guys have any idea what are these errors?

Thank you for your time.

Swfcatcher is a Chrome plugin. Try disabling it?
