Anyway, I have found a difference between my “personal gitlab account” and my “work for money” firefox profiles. Both are running the same Firefox version 93, and quite similar configuration.
Looking at the console, one of the cloudflare cookies has wrong time set when the browser tries to set it: https://megous.com/dl/tmp/9e8e10b5e5e57cb9.png This does not happen in my personal firefox profile.
But when I clear all cookies and local storage, my work profile keeps getting some https://megous.com/dl/tmp/de84fa2394b9b999.png experimental_subject_id cookie set and my personal does not https://megous.com/dl/tmp/dbcbf61395e86643.png
So it’s either cloudflare or gitlab doing some A/B testing. Probably trying to see how many people leave their platform when they block them from accessing their web UI for work.
Do you want a direct answer to your A/B tests here on the forum? Because I can provide one. LOL
