Anonymous Edit link is dead - cookies were preserved

[rfprogram]

No other users have my edit link, just me. As of last week, the edit link was functional. Cross-confirmed, the edits made then are still intact. And at that time, I made a point to preserve the umap cookies in my browser (Firefox). Confirmed we do have cookies from openstreetmap, umap, and openstreetmap.fr but we did reload a lot so FF is only showing the updates within the last hour. However, since then Firefox updated, and I don't know if that makes a difference. But even if I messed up and cleared cookies, it was on the white-list. Nothing from the above websites should have been deleted. There is no error message at all for the edit link. It's just a blank page. I switched VPN addresses in case we were on a blacklist there. Same result.
