To create a bookmarklet, create a new bookmark starting with javascript:, then the contents of minified.js.

minified.js

window.huluAdTimer = window.huluAdTimer || setInterval(function() { let volBtn = document.getElementsByClassName('controls__volume-button')[0], isMuted = volBtn.classList.contains('controls__volume-button--mute'), isAdbreak = document.getElementsByClassName('ad-container')[0].style.display=="block"; if((isAdbreak && !isMuted) || (!isAdbreak && isMuted)) volBtn.click(); }, 1000)

muter.js

// Here is an un-minified version
function muteAd() {
    let volBtn = document.getElementsByClassName('controls__volume-button')[0];
  
    let isMuted = volBtn.classList.contains('controls__volume-button--mute');
    let isAdbreak = document.getElementsByClassName('ad-container')[0].style.display=="block";
    
    let needsMute = isAdbreak && !isMuted;
    let needsUnmute = !isAdbreak && isMuted;

    if(needsMute || needsUnmute)
      volBtn.click();


    console.log("is " + (isAdbreak ? "" : "not ") + "ad");
    console.log("is " + (isMuted ? "" : "not ") + "muted");
    if(needsMute)
      console.log("muting");
    else if(needsUnmute)
      console.log("unmuting");
    else
      console.log("doing nothing");
}

let timerId = setInterval(muteAd, 1000)
