My laptop is running Ubuntu 19.10 as the only OS.
On the laptop Chrome is blocking cookies and third-party cookies for all websites. The small symbol with the red x lets me choose from "allow www... to set cookies" and "continue blocking cookies" but neither one works, i.e. allowing the website to set cookies doesn't actually let it set cookies.
I am posting here because using Chrome on my Android tablet does not have this problem with the exact same websites but FireFox on Ubuntu 19.10 does, so it seems to be an OS problem.
