Can't believe Valve pulled it off, honestly. Multi-year project to make Linux gaming a reality and then they launched it and not only did everyone love it, but they still love it. Honeymoon phase has worn off and people are still down with the Steam Deck. Even normies like it, not just Linux nerds.
There are filterlists for Ublock Origin that help with the Anti-adblock pop-ups, just in case the included ones don't already work for you. Also the Fastforward extension works well for bypassing Link shorteners.
