Can you take screenshot with open console in developer mode? For this you need to press F12 and click on console tab. Without this information I can't understand whats wrong.
On console will be showed the error messages with place where it happened (if you would expand the error it will be very helpful)

Thanks for this full description. It is very useful. As I see on your screenshot the problem there in broken parsing process. The extension can parse report table. So because there none of data present it generate an error that can't convert empty data.
It can't parse data because can't set variables with new selectors (an error with Identefer has already been declared.
The possible reason of this you don't turn off the extension from Chrome story and install extension from repository. If you switch off or delete on of them I hope all be ok. If not take a new screenshots please after this changes.

Extension that was switched off for example

I think that was the problem it is working now.
