I have a Firefox extension for creating PWAs (Progressive Web App), and had a profile setup for Youtube. The adblocker detected popup just appeared a couple weeks ago. So i just deleted the YouTube PWA profile, recreated it, and added Ublock back. Havent seen the popup or ads since.
Good detection, and I appreciated the free trial.
But, I don’t think I’d use it enough to warrent paying on it monthly. I did however find an app called Audire that is open-source, uses the API of Shazam, and is also free. Works very well.
