the Extension is a must have for everyone using YouTube, one thing to mention the Extension doesn't load properly all the times I'm using a FireFox fork, found people online complaining about the same thing, hope the dev addresses this issue in the NEXT update


Edit: a turn around fix that I use for now is a costume script

first install the Tampermonkey extension

second use this costume script(dont forget to edit the youtube and tampermonkey links):


// ==UserScript==
// @name Force Enhancer for YouTube
// @namespace past tampermonkey link here/
// @version 0.1
// @description Ensure Enhancer for YouTube loads consistently
// @author You
// @match past youtube link here /*
// @grant none
// ==/UserScript==

(function() {
'use strict';

// Function to check if Enhancer for YouTube is loaded
function checkEnhancerYouTube() {
// Look for specific elements that Enhancer for YouTube creates
const enhancerLoaded = document.querySelector('#enhancer-for-youtube-controls') ||
document.querySelector('[id^="enhancer-for-youtube"]');

if (!enhancerLoaded) {
console.log('Enhancer for YouTube not detected, forcing reload...');

// Create a temporary element to trigger mutation observers
const trigger = document.createElement('div');
trigger.id = 'enhancer-youtube-trigger';
trigger.style.display = 'none';
document.body.appendChild(trigger);

// Dispatch events that might wake up the extension
window.dispatchEvent(new Event('resize'));
document.dispatchEvent(new Event('readystatechange'));

// Clean up and try again
setTimeout(() => {
trigger.remove();
checkEnhancerYouTube();
}, 2000);
}
}

// Run after YouTube has loaded
if (document.readyState === 'complete') {
setTimeout(checkEnhancerYouTube, 3000);
} else {
window.addEventListener('load', () => {
setTimeout(checkEnhancerYouTube, 3000);
});
}
})();

Having stuttering and lag. For firefox shut it down he said!

Developer Says;
Extension v2.0.* randomly working in background tabs?! Controls not visible on page load?!
I know... No need to report these issues again and again, I have never been able to reproduce them...
The only way to fix them was to rewrite everything from scratch to create the version 3.0, and after months of hard work it is now available for Chrome and Edge so install it on those browsers because the version 3 will only be available for Firefox if Mozilla changes its review process because after more than 12 years publishing my extension on AMO there are things that I don't accept anymore!
