nba.com scoreboard intermittently renders empty after Firefox has been running for some time; issue persists across reloads, new tabs, private windows, containers, and site data clearing, and is resolved only by restarting Firefox. When Firefox has been running for some time, opening nba.com results in the scoreboard section being completely empty. The rest of the page loads normally (layout, navigation, static content), but live game data does not render. This issue does not occur immediately after a browser restart. It appears only after Firefox has been open and used for a while. Once the issue appears, it becomes persistent and cannot be resolved without restarting Firefox.
