Deny websites to mangle the clipboard content

[teknoraver]

An increasingly number of websites is starting to mangle the clipboard content after copy.

Usually they are newspapers which append the text "full article here: <URL> (C) Magazine Name" in the clipboard.

I find it rather annoying. Can we limit clipboard usage to user interaction (e.g. ^C, context menu) or allow it only after an event as it happens to enable sounds

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Is this still happening nowadays??

A lot

you can nullify the clipboard related javascript API's

but that will likely break a lot of websites which use richtext editors

This could be quite improved if the permission for clipboard events was a per-site preference.

The permission system could greatly improve (and user privacy and protection against dark patterns will) just by adding explicit permission request or event firing displayed in-browser when something like this happens.

I would see it just like the media devices popup panel when a microphone or camera are requested or simply accessed from a site through the satandard web apis. Something like -> "Website X wants to access clipboard to share this text: '...' ", but per site.
