I really like this addon. I have tried many of them, most either don't work OR... they want me to give up my entire privacy by tracking me continously. No way that I'm going to allow that (hey, there is a reason for me to be using FF in the first place ;).

Update 03/2021: this add-on remains simply the best - and the developer is keeping his promise: always trying to bring the best, and when the add-on gets broken somehow due to new Youtube/Google shit , he will make sure things start working again.

I simply love this add-on. KUDOS!
