OpenH264 codec NOT installing

more options

Hi, hi!

I just got my new MacBook Pro in the last weeks, installed the new Firefox in it but I could not use Netflix. I looked up add-ons and there is one plugin OpenH264 from Cisco that says it will install shortly but it does not. I tried to toggle it but that changed nothing. I really do not know what to do. Netflix runs normally on Safari, but Firefox is my browser of choice, it would be nice to be able to use there. I also do not know yet which other sites this might affect. Any ideas to what the problem is? How to fix it?

Thanks a lot

Is this question about desktop Firefox for MacBook Pro with Apple Silicon? Well, then 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.
