My company just started using DocuSign, and it looks really nice and handy! I find it insane however, that Firefox is not a "modern browser", and I either need to download an arbitrary smartphone app / another web browser (which is supposed to be built on standards?) to parttake in a simple videocall to verify my identity. I know it well it's easier to just support a single platform, but I personally don't like either Chromium, or technological monopolies that they are building. Please, consider giving users a free choice on an open web.
