Cannot enable thrid party cookies

[fimmugit]

What happened?

I am using Waterfox 6.0.20 on Windows 8.1. Here's my problem, I tried to create a new project in quantconnect.com (QC, need login) but a message popped up saying I need to enable third party cookie. So I did these:

1. go to Cookies and Site data, add an "Allow" exception for the QC site;

2. go to Enhanced Tracking Protection, add and exception similar to 1;

3. under Custom, I deselect everything and reloaded pages;

4. I also deselect enhance tracking for the site;

5 I also check to toggle some of the related configs under about:config.

PS: I have not tried Firefox because it is not supported.

all the above did not work to enable 3rd party cookies in Waterfox, message keeps popping up. I use other browsers (Edge, Vivaldi, Chrome, Opera etc.) and have no issue at all.

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.
