Why Photo in Firefox display "Firefox Can’t Open This Page: To protect your security, photos.google.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window."

Great job! Keep all google apps in a place. No need for many open tabs any more. Just two clicks and you're in. If you want more just a third click to open the app in a new tab. Time saving indeed! Also very quick response from the developer over a bug! Problem solved after deleting and reinstalling the add-on!

it doesn't work anymore after new update
