Additional Comments

My goal was to see if I could get Amazon Prime Video working on FreeBSD. Attempts with 64bit version failed completely, and i386 Wine is a mess on FreeBSD. So I switched my efforts over to Manjaro where it would be a little easier to setup. (Thus avoiding extra work if it didn't work.) The 32-Bit build of Firefox works fine if you use Louis Lenders' prefs.js tweaks. However, pages fail to see Widevine.

Browser Console gives out these error:

Calling navigator.requestMediaKeySystemAccess() (at https://www.amazon.com/gp/video/detail/B07G3MYBXX/ref=atv_hm_hom_3_c_rt5Geo_3_4) without passing a candidate MediaKeySystemConfiguration containing audioCapabilities or videoCapabilities is deprecated and will soon become unsupported.

Trying to play Widevine with no Windows Media Foundation. See https://support.mozilla.org/kb... ref=atv_hm_hom_3_c_rt5Geo_3_4

I have not investigated further to see if I can get Windows Media Foundation installed and working. But I will in the future. If I can get it working, I'll move my efforts over to FreeBSD.
