Unless Firefox also ships FDK-AAC-Stripped like Fedora and Flatpak (stripped ffmpeg with fdk_aac as part of freedesktop-sdk), there is little point in having OpenH264 for video decoding in Mozilla binaries (bug 1663844). Youtube could use H264+Opus, but prefers VP9 and AV1. Other websites require H264+AAC.
