https://connect.mozilla.org/t5/firefox-labs/web-apps-doesn-t-fit-on-lower-resolution-screens/m-p/133869#M5183 <P>I have this 1366x768 external monitor and im using it as a vertical screen. I tried placing the YT Music web app fullscreen onto it but for some reason it wouldn't scale down/transform to fit the screen. I tried placing a regular browser tab and it worked fine. Is there a setting to fix this?</P> Tue, 04 Aug 2026 11:13:00 GMT jsac 2026-08-04T11:13:00Z https://connect.mozilla.org/t5/firefox-labs/web-apps-doesn-t-fit-on-lower-resolution-screens/m-p/133869#M5183 <P>I have this 1366x768 external monitor and im using it as a vertical screen.
