If Microsoft wants to replace Internet Explorer with Edge, they must add ALL IE features to Edge. That means it must support ALL ActiveX controls and ALL IE plugins and Java. Until then, they better not remove IE from Windows 10! I use Firefox too, but I like IE better! Chrome also has banished support for Java and legacy plugins, so it is rather useless, like Edge. We will be forced to use Firefox only if we want full functionality. Not really a clever move Microsoft!
