In order to add photos to Shutterfly from google photos on Firefox, which is what Shutterfly likes, I have to enable 3rd party cookies. I have been trying and googling and searching support for some time now. The google instructions do not come close to matching what is on the commuter. The "support" instructions are in technical computer language which I don't get. So, please help me, but pretend you are explaining to your grandma (I may not be yours, but I am a grandma to 4 grandkids) and she's never used a computer before (I have, but I'm sick of wading through technical answers that don't match the computer and don't work). Thanks - I hope someone helps me. Grandma Mary
