Hi everyone, I have been discussing options for mitigating viewport-dimension fingerprinting with the Mozilla uplift team and I came up with a proposal for a non-letterboxing approach that might have some advantages over letterboxing: https://docs.google.com/document/d/1Pww4_gY59SPIK5dMxJchpevPs-MeeY5_mkxAKZdn... Maybe this is something we can discuss in Mexico City. I'd be interested to hear your thoughts. Thanks, Arthur
