I use BlockAda, It functions like a VPN which can be annoying if you use a VPN a lot but otherwise it is a simple on off switch for people who aren't very savvy with their phones.
It's Blokada. It's Polish for "blockade".
Or use Firefox Preview and uBlock Origin.
Yeah but that doesn’t block in-app ads
Add DNS66 from the fdroid store and you are set
Honest question, but which apps are both required (don't work in-browser) and don't serve ads from their own network (Youtube, Facebook)?
