Firefox dropped H264 support 1 year ago because of Google Play Store policies. This codec was required for interacting with iOS devices which did not have VP8. However, VP8 has been added since iOS 12.1, so it might be possible to use it now across all platforms.
While Firefox had to drop support for OpenH264 on Android, because of Google's Play Store policies. It is not true that only Chrome supports H264 on Android. Firefox switched to the Android platform encoder and decoder. So H264 work fine in recent versions of Firefox.
