Cannot play videos on Amazon/Netflix

Unable to play any videos on Amazon/Netflix. Just says Video unavailable. The same videos play just fine on Safari. Using a Mac Air M1.

After some investigation, it looks like the OpenH264 is not downloading (OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly.) Widevine is installed on the other hand.

Chosen solution

It's not about OpenH264, we use Widevine for a DRM content. It looks like you still need Rosetta, see Netflix, Hulu, Disney+ or Prime error after installing Firefox version 84 on Mac.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Installing Rosetta fixed it. Thank you so much!
