Any possibility to read clipboard data using javascript in Firefox without user triggered ctrl+v event. Chrome prompts user for clipboard access permission.

I am trying to read clipboard data using navigator.clipboard.readText() I get readText not a function whereas I can see that navigator.clipboard.writeText() is available. When I tried manually triggering ctrl+v I was able to access the data using event.clipboardData.getData().

I want a solution where the readText or getData should work without user intervention, provided the user is asked for permission before accessing clipboard, the way it happens in Chrome.

Clipboard.readText() is only supported for browser extensions in Firefox, not websites.

Clipboard.read() may work for you in the future, but it currently doesn't appear to be fully supported in Firefox and would also require the user to set the dom.events.asyncClipboard.dataTransfer preference to true.

It's a fairly new experimental feature, so it's not fully implemented by all browsers. Not to mention that it's pretty insecure to allow a website to read the user's clipboard without the user's knowledge.

Post the config changes I was able to see the read function, but did not work programatically. Do you know till when will the feature be available to use in future.

The Clipboard API is still a fairly new working draft specification. It's going to change frequently and possibly dramatically (in fact, the current draft was changed May 5, 2020) before it becomes an endorsed recommendation by W3C.

Until it's a recommendation (which could take a long time), it's still a non-standard feature that may fully supported in some browsers, but have partial or no support in others.
