Hi, I've been designing an invitation using canva on the fedex website. It looked good, but when I went back this week to the same site, I got an error: "Firefox Can’t Open This Page To protect your security, www.canva.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." Of course, I can't open it in a new window. I don't seem to be able to use this site at all now. This error wasn't there before. Is anyone else able to open canva via fedex's website? Is there something I can do to disable this security feature temporarily? https://www.office.fedex.com/default/canva is the link.
