It's 2021 right now.... you need a recent version, because they have updated a DRM plugin.

Lol I'm aware that it is 2021 and I'm not sure why you felt the need to mention that.

Anyways I solved it. Apparently the info in "About Firefox" is wrong because it's saying that I have the most up-to-date version, and that is incorrect. I googled "Firefox 78" and it turns out that there's a newer version of Firefox available for my Mac, so I downloaded it from the Firefox website. In Firefox 78, Netflix is working and plays video just fine for me.

Seems like this situation could be improved though because Firefox shouldn't be saying that you have the most up-to-date version when you don't, especially when Firefox's support article on "How to update Firefox" tells users to trust the "About Firefox" section and go there to check for new updates. I'd strongly recommend the team look into fixing it so that it tells users "you have Firefox 77 and Firefox 78 is available."

P.S. oh i didn't notice that the recent updates were in June 2020, obviously I thought they were June 2021. my mistake lol

Hi

I think we recently issued a small update to fix the issue you were experiencing.

I solved the problem by upgrading to Firefox 78.

HOWEVER, Firefox shouldn't be saying that you have the most up-to-date version when you don't, especially when Firefox's support article on "How to update Firefox" tells users to trust the "About Firefox" section and go there to check for new updates.

I'm on Firefox 92.1 and Netflix won't play. I've done all the suggested fix steps. What next? Netflix worked fine until today. KG
