I didn’t know Firefox didn’t have extensions on iOS. I would have called it Firefox android instead of mobile. I’m glad there’s still ways for iOS users to do this.
Adguard is in the category of questionable firewalls. I used it for a while and it was just too kludgey for me when there’s not many apps with ads that I use anymore. Android has free software for pretty much everything at this point.
I did use that for a while. Google was always finding ways to break it. I don’t use youtube on my phone often and when I had newpipe 9/10 times it was broken when I wanted to use it, so it didn’t make it onto my next phone.
