Works as intended. I love how my fan ramps up when I open the homepage of youtube. I even received the "this extension is slowing down firefox" notification once. Watching recommendations disappear one by one is fun. Wish youtube added the block feature. Great job, wish there was not a need for it. Also the ability to sync block list with firefox account would be great, I dualboot and use multiple pcs, I have to sync them up once a week to get rid of what youtube thinks I'd watch that week
