On android I find its also a good idea to have a system wide ad blocker solution because android and all their apps are so inundated by ads, so I recommend dns66 (which can be found on fdroid) which has multiple blocklists you can subscribe to. This will cover some ads thats are built directly into apps and almost all ads that would appear in websites on a browser. This helps a lot since some apps will open a browser window for -reasons- and they sometimes have their own internal browser or they will just use chrome by default, not respecting your default browser choice, and in those cases you cant have ublock installed to protect you and those pages are so ad-overloaded that finding what you are looking for is next to impossible.
