Been using this program for a few weeks and I think it's great in stopping ads on any application on Android (not just browsers).
Name of application: Blokada
'If you want to efficiently blocks ads, trackers and malwares, if want to save your data plan, make your device faster and protect your privacy with one application, Blokada is for you. It is free, secure and open source. Blokada works across all of your apps, not only the browser! It doesn't require root, supports both wifi and mobile networks, and is perfectly safe and simple to use. Just turn it on, and it will do the job silently!'
It's like uBlock but system wide.
