Indeed, Ive used firefox (since 2004) with uBlock (since 2015 or so) and have mac Mini(s) connected to TVs; use wireless mouse to enjoy the web from my couch or in my room. There are zero ads or popups seen.

On other TVs like my Roku i do pay for a few streaming services with ads and get bombarded with ads on that tv. But its a group tv that many use.
