HBOMAX

[member=4833]sameck[/member] It seems it's has nothing to do with whatever browser you're trying to use but rather that HBO isn't working on Linux. Read here https://arstechnica.com/gadgets/2020/08/...-the-cold/ here's an excerpt

the root cause of the problem is that the Widevine DRM attempting to protect HBO Max's content from pirates is refusing to recognize any Linux system as a known platform. We saw the same thing happen in January, when CBS All Access suddenly stopped working on Linux in the same way. When we asked CBS executives if they had enabled the Verified Media Path (VMP) requirement on their Widevine server, they suddenly clammed up—but later that day, the service miraculously worked for Linux users again.

and here https://dangillmor.com/2020/08/10/hbo-ha...nux-users/ the author explains that he contacted HBOMAX support requesting assistance since he could no longer use the service on Ubuntu and said

Here’s what “customer support” told me in an email: “We do not support usage under this operating system.”

So, sadly it'd appear you can not longer play HBOMAX content on Linux, at least for now.
