Works, but too well... Rated 4 out of 5 stars

It needs some customization options because this addon has been blocking Google shopping for me. It won't even load the pages, I just get a blank page.

This review is for a previous version of the add-on (1.0). 

Feel free to give the version 1.2.1 a try. It's awaiting review atm so you'll have to get it from the versions history page.
