I have been super happy downloading the free adguard dns profile on my iphone and blocking ads across the entire spectrum. Makes reading on internet so much better. Here is the link if anyone is wondering.

Thanks for sharing, good advice!

I will check it out. I like Firefox Focus because in addition to built in blocking, it restricts me to one tab. Remarkably, that has never been a problem.
