2026-08-18	Mo*****	uBlock Origin is honestly one of the best Firefox extensions. It works great, and YouTube ad blocking works perfectly for me. I especially find the one-star reviews saying “YouTube ad blocker not working” funny, because I’m having the complete opposite experience. No annoying YouTube ads, and the extension just does its job. Definitely deserves 5 stars.
