I'm still getting notifications about this a year later 😂
Here's some untested code you could try out:

const observer = new MutationObserver(mutations => {
    // the DOM was modified, run the ad-b-gone.js script here
})

observer.observe(document.body, { subtree: true, childList: true })

I've included this in this bookmarklet, thanks!
