This is a JavaScript script for unsubscribing from YouTube channels. The script automatically clicks the unsubscribe button for each channel on the page and removes it from the DOM. The script uses the YouTube DOM elements to perform the unsubscribe action, so it should work regardless of changes to the YouTube website design. To use the script,…

unsubscribe-all-youtube-channels.js

// Get the total number of channels to unsubscribe
var channelCount = document.querySelectorAll("ytd-channel-renderer:not(.ytd-item-section-renderer)").length;

// Call the timer function
unsubscribeTimer();

function unsubscribeTimer() {
  // Return if there are no channels left to unsubscribe
  if (channelCount === 0) {
    return;
  }

  // Get the element with the subscribe button and click it
  var subscribeBtn = document.querySelector('.ytd-subscribe-button-renderer');
  subscribeBtn.click();

  setTimeout(function() {
    // Get the unsubscribe button and click it
    var unsubscribeBtn = document.getElementById("confirm-button");
    unsubscribeBtn.click();
    
    // Update the channel count and log the result
    channelCount--;
    console.log(channelCount + " remaining");

    // Remove the channel from the DOM
    var channelToRemove = document.querySelector("ytd-channel-renderer");
    channelToRemove.parentNode.removeChild(channelToRemove);

    // Call the timer function again
    unsubscribeTimer();
  }, 250);
}

Doesn't seem to be working (at least in Firefox) - the unsubscribe button -looks- like it gets clicked, the objects get removed, but if I refresh then suddenly all my subscriptions are back.

EDIT:

If it helps, I get this when I try to refresh the screen (which shows all the buttons/channels for me again, visually) and then re-run the script:
