Is there a way to play Netflix on the PC as a small player?

So what I mean by that is e.g. I play World of Warcraft with a full screen and would like to play Netflix in the top right or left as a small player. That means I can easily continue to play full screen World of Warcraft and at the same time a series. Is that possible? I don't want to play World of Warcraft in windowed mode either, it doesn't work.

I think that's a feature of the Opera gx browser.

Should go with Firefox

How exactly is that supposed to work? What do I have to click there?

What is the name of this feature? And what exactly do I have to do? I opened Netflix.
