No idea, but it seems to be using Akamai Player: https://player.akamai.com/

It seems to have an event called "autoplayblocked": https://developer.akamai.com/tools/AdaptiveMediaPlayer/docs/...

The entire video loads but Firefox does block it from playing. Am on version 70 and have disabled autoplay as well. But I've come across other sites that are somehow able to play a video even with autoplay blocked.

It doesn't autoplay for me (using Firefox 70.0)

In fact, in my console there's a message that says this:

"Autoplay is only allowed when approved by the user, the site is activated by the user, or media is muted."

I use the Brave browser due to these kinds of things

i think it's blocked until you interact with something on the page, even if it's not the video

Idk, I use Chrome, works like a charm.
