too much access permission. Not worth giving my passwords to these developers.

Лучший блокиратор рекламы и слежки ! Спасибо вам!

Melhor bloqueador de anúncios. The Best

THANK YOU for all the continued hard work you all provide us

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! 😁

You can try my custom add-on collection on Firefox Nightly mobile here:
User ID: 17588160
Name: Sprinkle-Bally-s-Add-Ons

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.

Firefox instantly crashes whenever I open fandom wikia, usps package tracking, tumblr, and ign i have no idea what the correlation with these sites are but please fix this this add-on is completely unusable! Even Mozilla's website crashes!!!!
