I feel like Firefox should implement these features, they are excellent features that even though may have their risks are risks well understood by many firefox users. Keeping them disabled by default (and behind flags) is also a possible choice. I think features like these would encourage companies web apps and at the end be safer than downloading a native binary with much much more access to my device's data.
