As reported in https://webcompat.com/issues/65659, one cannot log into celesia-dm.wikidot.com while in a private browsing window or with strict ETP on.

While trying to log in, I see these two requests are blocked, so it may be related to them:

http://stats.g.doubleclick.net/dc.js
http://edge.quantserve.com/quant.js

It turns out that this issue has nothing to do with ETP or TP. I can reproduce this issue with or without ETP.

I have found the root cause of it. This webcompact issue is caused by the cookie sameSite schemeful. Flipping network.cookie.sameSite.schemeful to false will resolve this issue.

No longer blocks: tp-breakage

Summary: Cannot log into with Strict mode on → Cannot log into celesia-dm.wikidot.com when schemeful sameSite cookie is on

FWIW, I can't reproduce this by enable sameSite schemful on chrome.

Can you still reproduce this? Did you create an account for this?
