Am I missing something Rated 1 out of 5 stars

OK I must be an idiot but when Im on a website where I want to capture the screen and I click on the Screenshot button all it does is load a blank page with this in the address bar:

This review is for a previous version of the add-on (1.0.3). 

Could you tell us the URL where you experienced the issue?

Thanks.
