Dependable, trustworthy, reliable, and the developer keeps up the code. I have used EUVD for years as my #1 go to web VR. This app work exceptionally well and the developer is very quick to respond to questions of all types. Dishita is also extremely quick to fix any issues brought on by the constant changes that YouTube makes. Fantastic Firefox extension that works as advertised and is worth the asking price many times over. Please use it responsibly.
