Pop ups are blocked, but the URL is on the allowed list. I am clicking on the orange button and nothing happens at all... I have tried closing/reopening the browser, too. SO............
I opened Google Chrome, went to the shop, logged in and loaded pictures into both areas. So this issue is a Firefox issue on my end. Sorry I bothered you with this! At least now if someone else seems to be having the same issue you can suggest they try a different browser.
