[BUG] "Paste" button appearing when LEFT CLICK

[ghiki]

Still happening the same issue with "dom.event.clipboardevents.enable" switched to "false"

this is my compose yaml:

services:
  chromium_cont:
    #image: lscr.io/linuxserver/chromium:latest
    image: lscr.io/linuxserver/chromium:kasm
    #This is just how firefox decided to implement the seemless clipboard API, to disable this in about:config set dom.event.clipboardevents.enabled to false.

btw, if i set "clipboardevents" to "false", i cant copy anything from browser to outside the browser

I have discussed this before but I will make zero effort to do anything to bypass Firefox's default seamless clipboard behavior.

This is how they want it to work, if you want them to add a toggle to work like chromium tell them that.

My level of care on this issue is 0, so unless someone else picks up the torch this is how it will always be.
