Not sure why, but unfortunately using that list in uBlock Origin (latest Firefox 77) does not produce the same result as using the "I don't care about cookies" extension;

That's odd; it appears they are using a different cookie 'popup' depending on the browser/OS...?
I tested on Ubuntu and macOS with the latest Firefox (clean profile) and Chromium and i get the cookie popup/wall, even with ALL default uBO filter lists enabled, and also with the IDCAC list enabled in uBO. Screenshot: https://imgur.com/jcr4EuP
However i just tested with https://www.browserling.com/ which uses Windows 7/Internet Explorer 11 and here i do not see the 'cookie popup/wall' but instead i see a blue 'cookie banner' (which is easier to block with uBO.)
That's weird. I'm on Linux but enabled privacy.resistFingerprinting in about:config, which sets the user agent to a standard Windows one (same as Tor Browser iirc) and also brings over a bunch of other Tor Browser features. Only downside is it reduces timer precision which makes some games lag, so occasionally I have to turn it off for a bit.
