Firefox 127 fully supports the async clipboard API

This is about https://caniuse.com/async-clipboard

https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/127 says "The async Clipboard API is now fully supported."

I would send a PR, but am not sure about the current note for Firefox and how to update it.

The specification also mentions supporting the "clipboard-write" permission as part of the API which I don't think Firefox supports yet. So based on that I don't think it's really fully supported?

The permissions situation for clipboard access is complicated, and I don't know the details. It looks like the security teams of different browsers disagree about what the model should be, but that it's possible to use the API in all browsers without really know about these details, by just ensuring that navigator.clipboard.writeText() and similar are called from click event handlers.

Looping in @EdgarChen who implemented this in Firefox and @saschanaz who filed w3c/clipboard-apis#164.

Both clipboard-read and clipboard-write permissions are Blink only as AFAIK standards positions are negative from Mozilla and Apple.

Thanks for added context! Have switched support to full and added some notes on the security considerations.
