Was introduced by my post-secondary school. Before that, i lived in a place where the internet is heavily censored, and to get to YouTube, we either had to use proxy websites that broke the website or go to sketchy mirroring websites like YouPak that's infested with malicious redirects. Had i known about your extension then, i could've solved that problem with malicious redirects and didn't have to speak out against using it. Now i use YouTube to MP3 sites with uBlock in the background and it works well. Plus, whenever i accidentally click on a mobile ad outside Firefox, 𝘵𝘩𝘦 𝘳𝘦𝘥𝘪𝘳𝘦𝘤𝘵 𝘪𝘴 𝘢𝘶𝘵𝘰𝘮𝘢𝘵𝘪𝘤𝘢𝘭𝘭𝘺 𝘣𝘭𝘰𝘤𝘬𝘦𝘥 𝘣𝘺 𝘶𝘉𝘭𝘰𝘤𝘬'𝘴 𝘱𝘳𝘪𝘷𝘢𝘤𝘺 𝘧𝘪𝘭𝘵𝘦𝘳𝘴! 😁

Amazing if not outright essential add-on at this point. Browsing sites without it is like night and day, there are just so many obnoxious ads plastered everywhere. The ability to manually block elements helps remove the few things that get by it.
